Explain the melting of a solid in terms of molecules and energy​

Answers

Answer 1
When you melt a solid the heat creates energy, when you heat up molecules they will move quicker and start to somewhat break apart into a liquid structure.
Answer 2

Heat generates energy when you melt a solid; as you heat up molecules, they move faster and begin to break apart into a liquid form.

What is the melting point?

The melting point is the point at which a substance transforms from a solid to a liquid.

The melting point of a liquid is the temperature at which it transforms from a solid to a liquid at atmospheric pressure. This is the point where the liquid and solid phases are in balance.

Heat generates energy when you melt a solid; as you heat up molecules, they move faster and begin to break apart into a liquid form.

The kinetic energy of the molecule is due to the movement of the molecule as the temperature of the system increases the melting point comes closer.

As the temperature increases the kinetic energy of the molecule increases.

Hence the energy, melting point, and temperature relatively affect each other.

Answer:

50N increasing

Explanation:

it looks like we want the net force. this is the sum of all forces acting on the object. here the problem is extremely simplified and we are even given the values of force. this looks like the rocket is producing an upward force of 160 newtons. it also looks like maybe weight (gravity) and drag (air resistance) are producing downward force against the rocket. we can say those would be subtracting from the amount of upwards force. so 160-40-70=50N. since the force is positive that means we will still have a magnitude of force vector that points upward and so we will increase.

what determines the color of light?

1. brightness
2. wavelength
3. amplitude
4. reflection rate

Answers

The answer is wavelength because The wavelength of visible light determines the color that the light appears. Light with the longest wavelength appears red, and light with the shortest wavelength appears violet. ... The wavelengths of visible light that an object reflects or transmits determine the color that the object appears to the human eye

Answer:

2. wavelength

Explanation:

Light moves in waves. Light waves are different from sound waves in that light travels in transverse waves (as opposed to longitudinal, which is how sound waves travel). A light wave that travels in a direction is called a light ray.

Just like other waves, light waves have a wavelength and amplitude. The wavelength determines the color; we will learn more about this in the lesson on color. The amplitude of a light wave determines the brightness. Just as large amplitudes in sound waves result in sounds with greater intensities (louder sounds), large amplitudes in light waves result in light with greater intensity (brighter light).

A car travels at 12 m/s. The car then accelerates at 3 m/s2 until it reaches a speed of 18m/s.
Use the formula: (final velocity)2 – (initial velocity)2 = 2 x acceleration * distance
Calculate the distance the car travels.
A
2 m
B
6 m
С
30 m
D
60 m

Answers

Answer:

С. 30 m

Explanation:

Given the following data;

Initial velocity, U = 12m/s

Final velocity, V = 18m/s

Acceleration, a = 3m/s²

To find the distance, we would use the third equation of motion;

V ² = U² + 2aS

Substituting into the equation, we have

18² = 12² + 2*3*S

324 = 144 + 6S

6S = 324 - 144

6S = 180

S = 180/6

Distance, S = 30 meters.

Three gases are at the same temperature and so have the same kinetic energy . The atomic mass of gas 1 is 10amu the atomic mass of gas 2 is 25 and atomic mass of gas 3 is 8. Which gas will have the greatest velocity ?​

Answers

Answer:

We mentioned in the study section of Lecture 2 that hydrogen and oxygen combine in the ratio of 1 to 8, but that this is not enough information for leading to the conclusion that two hydrogen atoms combine with one of oxygen to form a water molecule. A key idea is attributed to Avagadro who said that equal volumes of gas (at the same temperature and pressure) contain equal numbers of constituent atoms or molecules. Experiments show that two liters of hydrogen gas will combine with one liter of oxygen gas to form two liters of water vapor. Each hydrogen molecule in hydrogen gas consists of two hydrogen atoms bonded together. Likewise, two oxygen atoms bind to make a oxygen molecule.

A "model" of a physical process is used to represent what one actually observes, even though this is an "ideal" model and not expected to be correct in all respects. However, it is a good enough model to explain many of the properties of gases with sufficient accuracy.

The motion of gas particles can be used to explain the pressure exerted and the temperature of a gas. The pressure on a surface is due to the force on that surface divided by its area. The force comes about from the multiple impacts of individual gas particles. Temperature, on the other hand, is DEFINED in terms of the average kinetic energy assocated with the motion of the gas particles. The greater the kinetic energy, the greater the temperature. See the apparatus shown in Figure 7.6 of the text which gives a simple way of measuring the distributions of speeds of atomic particles.

To visualize how gas particles colliding with a container create pressure, see Website II.

Gas particles move in all possible directions with differing speeds. The Kinetic Energy (KE) of a gas particle is equal to 1/2 its mass times its speeds squared. That is KE = 1/2 M x V2 , where M is the mass of the gas particle and V is its speed. The gas particles have a range of speeds, just like cars on a road, but it is the average of the speed squared times the mass, or the average kinetic energy which characterizes the temperature of a gas.

High temperature is associated with high kinetic energies and low temperatures are associated with low kinetic energies. However, keep in mind that the kinetic energy, and in this case the temperature, is proportional to the mass times the speed squared. So heavy particles moving more slowly will have the same kinetic energy as light particles moving more rapidly. Also, because the kinetic energy varies as the square of the speed, if two particles have the same mass, but one moves twice as fast as the other, it will have four times the kinetic energy (or temperature).

If temperature is associated with kinetic energy of a gas, one could ask at this point what controls the temperature of solids and liquids. It turns out that it is the kinetic energy of the constituent atoms and molecules that characterize the temperature of liquids and solids as well. We show in class a transparency picturing a solid with its atoms rigidly connected to each other. We will discuss more about liquids and solids in the next lecture, based on chapter 8. However, for now, let's keep in mind that the atoms or molecules in a solid, although bound to its neighbors in a rigid structure, can oscillate back and forth, and it is this motion that characterizes the temperature of a solid (or in a similar manner, of a liquid as well). As before, rapid oscillations mean high temperatures, and slower oscillations are lower temperatures.

4 - The Three Temperature Scales

There are three temperature scales. In the United States, we commonly use the Farenheit scale while in most other nations, the Celsius or Centigrade scale is used. Figure 7.10 shows these two scales side by side. Water boils at 212 degrees Farenheit or 100 degrees Centigrade. Water freezes at 32 degrees Farenheit or zero degrees Centigrade. However, the most important temperature scale for scientific calculations is the absolute temperature scale, or the Kelvin scale. Zero degrees Kelvin is the coldest possible temperature: it can be physically interpreted as the situation where the atoms or molecules have zero kinetic energy...so this is a very natural temperature scale. Zero degrees Kelvin is also -273 degrees Centigrade. Water freezes at +273 degrees Kelvin and zero degrees Centigrate. Hence, a difference of one degree is the same on the Centigrade and Kelvin scales, but the zero points are different.

A car traveling at 5m/s starts to speed up after 3 seconds its velocity has increased to 11 m/s what is its acceleration

Answers

Answer:

a=(v-u)/t

Explanation:

a =(11-5)/3

a= 8/3

a= 2.6 m/s

The acceleration of the car is 2 m/s².

What is acceleration?

Acceleration is the rate at which speed and direction of velocity vary over time. A point or object going straight ahead is accelerated when it accelerates or decelerates.

Even if the speed is constant, motion on a circle accelerates because the direction is always shifting. Both effects contribute to the acceleration for all other motions.

Acceleration is a vector quantity with and SI unit of it is meter/second².

Given parameters:

Initial speed of the car: u = 5 m/s.

Final speed of the car: v = 11 m/s.

Time interval: t = 3 second.

Change is speed = final speed - initial speed

= 11 m/s - 5 m/s

= 6 m/s.

Hence, its acceleration is = change in speed / time interval

= 6/3 m/s²

= 2 m/s².

What happens to the force between charged and uncharged objects as the distance between them decreases?

Also In electrostatics, the electrical force between two charged objects is inversely related to the distance of separation between the two objects. ... And decreasing the separation distance between objects increases the force of attraction or repulsion between the objects.

Hope this helps have a awesome night/day❤️✨

Explanation:

Nothing, until those two objects physically touch each other; contact aligns polarity among the now single shared mass.

(Your question never states if both objects are unique or similar polar charges, so I just assumed they were both neutral objects existing within an electric field.)

So a better question would then be, what is gravity’s relationship with an electric field?

You could solve this with the following: confine the electric field’s volume to a set variable (never increasing nor decreasing in size or shape); density is variable and easily definable. This creates the limit to build upon. This density has to be fluid and has electron mass (full of electrons at rest mass, so with substance but no movement). Within, create a closed system (the hard part in this equation; outside interference like ambient light will eschew results) where each variable of kinetic energy then is accounted for or measurable (including heat and light, and the physical movement of the two objects)

Determine the mass for both objects, calculate gravity for both and each body’s inertia on the other as a sum over distance. record results. Polarity is shared across the masses until there is no longer inertia (one mass or contact).

Explanation:

Impulse is given by the product of force and time. It is denoted by J. So,

Constant velocity means that the object in motion is moving in a straight line at a constant speed. You know this as in the first panel each arrow representing each second is the same width apart, therefore you know the cyclists are moving at a constant velocity. Compare this to the second box representing changing speed. The arrows are different lengths meaning each second the cyclists are moving at a different speed and are not moving at a constant velocity.

A 96 kg man is standing in an elevator. The man experiences a net force when the elevator moves at an acceleration of 4.0 m/s2 upward and downward. Find both net forces

Answers

Answer:

The net upward force the man experiences is approximately 1,324.8 N

The net downward force the man experienced is approximately 556.8 N

Explanation:

The given mass of the man, m = 96 kg

The acceleration of the elevator, a = 4.0 m/s²

According to Newton's third law of motion which states that action ad reaction are equal and opposite, when the elevator moves upwards, we have;

The net force the man experiences, F = Gravitational force, m·g + The force of the elevator pushing upwards, m·a

∴ ↑F = m·g + m·a

Where;

F = The net force the man experiences

m = The mass of the man = 96 kg

g = The acceleration due to gravity ≈ 9.8 m/s²

a = The acceleration of the elevator = 4 m/s²

∴ ↑F = 96 kg × 9.8 m/s² + 96 kg × 4 m/s² ≈ 1,324.8 N

The net upward force the man experiences ≈ 1,324.8 N

When the elevator moves downwards, we have;

The net force the man experiences, F = Gravitational force, m·g + The loss of the gravitational force as the floor moves further downwards, -(m·a)

∴ F = m·g + -(m·a) = m·g - m·a

F = m·g - m·a

∴ ↓F = 96 kg × 9.8 m/s² - 96 k × 4 m/s² ≈ 556.8 N

The net downward force the man experienced ≈ 556.8 N
