A carnot heat pump maintains the temperature of a room at 22°c and consumes 2 kw of power when operating. if the outside temperature is 3°c, determine the rate of heat added to the room.

Answers

Answer 1

The rate of heat added to the room by the Carnot heat pump is 31.25 kW.

To determine the rate of heat added to the room by the Carnot heat pump, we need to use the Carnot cycle efficiency equation:

Efficiency = (Th - Tc) / Th where Th is the temperature of the hot reservoir (the room), Tc is the temperature of the cold reservoir (the outside), and the efficiency is the ratio of the work done by the heat pump to the heat input.

We know that the temperature of the room is maintained at 22°C, so Th = 22°C = 295 K. The temperature of the outside is 3°C, so Tc = 3°C = 276 K.

The power consumed by the heat pump is 2 kW, so the rate of work done by the heat pump is 2 kW.

Now we can use the efficiency equation to solve for the rate of heat added to the room:

Efficiency = (Th - Tc) / Th

Efficiency = (295 - 276) / 295

Efficiency = 0.064

Rate of heat added = Rate of work / Efficiency

Rate of heat added = 2 kW / 0.064

Rate of heat added = 31.25 kW

Therefore, the rate of heat added to the room by the Carnot heat pump is 31.25 kW.

Explain why dissolving is classified as a physical change.

Answers

Answer:

dissolving is classified as a physical change because it can be reversed back to its original form

explanation:

Dissolving is an example of a reversible change. For example, when salt is mixed with water it disappears because it dissolves in the water to make salty water. But we can get the salt can back again by boiling off the water. That leaves the salt behind.

You start with 100mL of 14M HNO3 and 10grams of copper metal. How many moles of the nitrogen dioxide gas will be produced?

Answers

Answer:

0.316 moles are produced.

Explanation:

We state the redox reaction:

4HNO₃   + Cu   →  Cu(NO₃)₂ + 2NO₂ + 2H₂O

We need to determine the limting reactant:

0.1 L . 14 M = 1.4 moles

10 g . 1mol/ 63.54g =0.158 mol

Cu is the limiting reactant. Let's see

4 moles of acid need 1 mol of Cu to react

1.4 moles of acid may react to (4 . 1) / 1.4 = 0.35 moles

We do not have enough Cu.

1 mol of Cu can produce 1 mol of NO₂

Then 0.158 moles will produce, 0.316 moles. (double of moles)

Answers

Answer:

The usual cause of sea breeze is the difference in specific heat capacity between land and water Land heats and cools more quickly than water. What is the cause of a sea breeze? The air over the land is warmed and rises, to a greater temperature than that over the sea.

Explanation:

Your answer is C ! <3

The difference in specific heat capacity between land and water is the cause of sea breeze.

What is sea breeze?

land and ocean heat up at different rates, sea breezes often occur during hot, summer days. The land surface warms up more quickly than the water surface during the day. As a result, the air above land is warmer than that over water.

Just to refresh your memory, warmer air is lighter than cooler air. Warm air rises as a result. As a result, the warmer air above the ground is rising. The cooler air above the water is moving across the surface of the land to replace the rising heated air as it rises over the land.

This is the sea breeze, which is seen at the top of the next picture. The land breeze that happens is seen at the bottom of the following picture.

Therefore, The difference in specific heat capacity between land and water is the cause of sea breeze.

Element with 6s subshell

Explanation:

Reactivity of an element depends on the electronic configuration and position of element in the periodic table as reactivity increases as we go down the periodic table.

This is so because number of shell increases as move down the periodic table and the last electron is further away from the nucleus.

Element with 6s subshell is the largest among 3s and 4s subshell and has more number of shells so it will react more than 3s and 4s subshell.

Hence, the correct answer is "Element with 6s subshell".

The solubility of AgNO3 at 10° and 20°C are 170g and 222g per 100g H2O. What is the sign of change of heat of solution for AgNO3?

Answers

Answer:

The sign of change of heat of solution is positive

Explanation:

The dissolution of AgNO3 in water is represented by the equation;

AgNO3(s) --------> Ag^+(aq) + NO3^-(aq)

We can see from the question that as the temperature was increased from 10° to 20°C the solubility of the solute increased from  170g to 222g per 100g of H2O.

This implies that the solubility of the solute increases with increase in temperature.

If a reaction moves in the forward direction when the temperature is increased, then the reaction is endothermic. If the reaction is endothermic, the sign of change of heat of solution is positive.
