Imagine you are at your favorite beach. The sun is shining and you are enjoying the ocean breeze. The temperature is about 89F. You take your shoes off and realize that the sand is almost too hot to walk on. You run to the water's edge to wet your feet after the walk over the sand and realize that the water is almost too cold. Explain the temperature difference between the sand and water using Thermodynamics.

Answers

Answer 1

Answer:

The specific heat of water is more specific than the heat of sand, therefore, it will take more energy to raise the same amount of water with the same temperature.

Explanation:

The temp is 89 F so, 31.67° C

The specific heat of  the water is 4.184 J/g° C

The specific heat of the sand is 0.290 J/ g° C

The heat is the amount  of energy that is needed to raise the temp. of the substance

You will need a lot more energy to raise the temp of the water then of the same amount of sand, therefore, because of the specific lower heat of the sand it will raise it's temperature quicker compared to water.

Chlorine gas is part of BrIClHOF, which are diatomic gasses. So Cl₂

Looking at the periodic table potassium K has an ion charge of +1 and chlorine Cl has an ion charge of -1, so in a balanced compound they will be written as KCl

Determine the final temperature of a mixture of 50 grams of water at 10 C added to 120 grams of water at 80 C. Show all work. Use the simulator to check your answer. (Hint: This is a weighted average.)

Answers

Answer: 59.41

Explanation:

The final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

Specific heat can be defined as the amount of heat required to raise the temperature of 1 g of substance by 1-degree celsius.

The amount of heat lost and the heat gained have been equal.

Heat = mass × specific heat × change in temperature

Thus,

mc[tex]\Delta[/tex]T = mc[tex]\Delta[/tex]T

50 g × (10 - x) = 120 × (x - 80)

500 - 50x = 120x - 9600

70x = 9100

x = 130

Thus, the final temperature of the system has been 130[tex]\rm ^\circ C[/tex].

convert kilometers to AU? (Hint: 1 AU = 149,598,000 km)

Answers

Answer:

Multiply the length value by 6.68456e-9

Explanation:

The question involves converting from one unit (kilometers) to another unit (Au)

From the question;

149,598,000 km = 1 AU

1 km = x

Cross multiplying;

1  * 1 = x * 149,598,000

1 = 149,598,000x

x = 1 / 149,598,000

x = 6.68456e-9

To convert kilometer to Au; Multiply the length value by 6.68456e-9

It takes 5.54 mL of a 2.18 M NaOH solution to neutralize 6.19 mL of an HCl solution. What is the concentration of the HCl solution? Do not include units in your
answer. Round to the tenths place or further.

Answers

Answer:

2 M

Explanation:

NaOH + HCl --> NaCl + H2O,

5.54 mL = .00545 L,

If we consider 2.18 M, M [molarity] = mol/L, so we have 2.18 mol/L. From this we can get the moles of NaOH.

.00545 L *  2.18 mol/L ≈ .0121 mol

The concentration of HCl can be found from the following:

.0121 mol = .00619(x) [where x = concentration of HCl]

x = 1.955 M ≈ 2 M

We equate the two as we require the same amount in order to neutralize the base.

_________deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses

Lesson 2.12

Question 3 options:

Density


Thermohaline currents


Salinity


Polar ice caps

Answers

Answer:

its B) Thermohaline currents  Sorry if its wrong but im sure this could be it

Explanation:These deep-ocean currents are driven by differences in the water's density, which is controlled by temperature (thermo) and salinity (haline). This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice.

Thermohaline currents deep-sea currents that occur because of differences between the salinity and temperature characteristics of water masses

What is thermohaline currents?

Thermohaline currents is also known as 'the ocean conveyor belt' or 'the global conveyor belt'. It is a part of the large scale ocean circulations.

As the name thermohaline suggested that, 'thermo' means heat and 'haline' refers to the salt content. So, when there is a great difference in the temperature and the salt content deep sea currents occur.

Hence option (2) is correct i.e. thermohaline currents occur due to temperature and salinity difference.

The ideal gas equation can be defined as an equation that describes the behavior of an ideal gas. This equation gives by the product of the volume and pressure is equal to the product of the moles of gas, gas constant, and absolute temperature.

The mathematical form of the ideal gas law is given as follows:

PV = nRT

Where n is the moles, V is the volume, R is the universal gas constant and P is the pressure.

The temperature of the N₂ , T =  0° C = 273 K

The pressure of the gas at STP, P = 1 atm

The value of the universal gas constant, R = 0.082 atm L/K mol

The number of moles of N₂, n = 0.881 mol

Fill in the values n, R, P, and T in the equation, and we get:

1 × V = 0.881 × 0.082 × 273

V = 19.72 L

The percent composition of nitrogen, hydrogen, sulfur , oxygen in ammonium sulfate is 21.18%, 6.05%,24.21%,48.43% respectively.

What is percent composition?

The percent composition  is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.It helps in elemental analysis of a given compound by giving proportions in which they are present.

Percent composition of N= 28/132.14×100=21.18%

Percent composition of H=8/132.14×100=6.05%

Percent composition of S=32/132.14×100=24.21%

Percent composition of O=64/132.14×100=48.43%.
