Why Decreasing Container Volume Doesn't Increase Temperature?

In summary, decreasing container volume does not increase temperature because temperature is dependent on the average kinetic energy of particles, not the volume of the container. However, decreasing container volume can increase pressure, but only affects temperature if there is a change in the average kinetic energy of the particles. Exceptions to this rule include chemical reactions that release energy, which can lead to an increase in temperature. Overall, decreasing container volume does not always result in an increased temperature and there are other factors that can influence the temperature of a substance.

I understand that as temperature increases the volume of the container will also rise.
Due to the particles having more KE and coming in contact with the container walls more
frequently and with more force.

My question is.. why isn't the inverse true?

When you decrease the volume of the container shouldn't the temperature increase.
Is it because KE or temperature is a constant?

I could you some clarification. Thanks.

In adiabatic compression temperature of gas goes up.
 

Related to Why Decreasing Container Volume Doesn't Increase Temperature?

1. Why does decreasing container volume not increase temperature?

Decreasing container volume does not increase temperature because temperature is a measure of the average kinetic energy of particles in a substance. When the volume of a container decreases, the same amount of particles are now confined in a smaller space, resulting in an increase in pressure. This increase in pressure causes the particles to collide more frequently, but with the same amount of energy. Therefore, the average kinetic energy, or temperature, remains unchanged.

2. Does decreasing container volume always result in increased temperature?

No, decreasing container volume does not always result in increased temperature. As discussed, the temperature of a substance is dependent on the average kinetic energy of particles, not the volume of the container. Other factors, such as the type of substance, can also play a role in determining the temperature.

3. How does decreasing container volume affect pressure and temperature?

Decreasing container volume increases pressure, but does not necessarily affect temperature. As the volume decreases, the same amount of particles are now confined in a smaller space, leading to an increase in pressure. However, the temperature will only change if there is a change in the average kinetic energy of the particles.

4. Can decreasing container volume lead to a decrease in temperature?

Yes, decreasing container volume can lead to a decrease in temperature if the particles in the substance lose kinetic energy. This could occur if the particles release energy in the form of heat, causing the average kinetic energy and temperature to decrease.

5. Are there any exceptions to the rule that decreasing container volume does not increase temperature?

Yes, there are some exceptions. In some cases, decreasing container volume can result in an increase in temperature if the particles in the substance undergo a chemical reaction that releases energy. This energy can then be absorbed by the particles, leading to an increase in their average kinetic energy and temperature.
