Is internal energy of cooling curve decrease ?

you gotta be specific in your question, but from what i learned it decreases since the temperature decreases, and average kinetic energy is related to temperature.

Hope it helped

Yes, generally. As temp goes down, internal energy decreases, if there are no chemical changes.

The internal energy of a substance can decrease during a cooling process, as energy is typically transferred from the substance to its surroundings. This loss of energy results in a decrease in the internal energy of the substance. The cooling curve is a graphical representation of the cooling process, typically showing the change in temperature over time. As the substance cools, its internal energy decreases, leading to a decrease in temperature.

To determine whether the internal energy of a cooling curve decreases, we need to understand what a cooling curve represents and how it relates to the internal energy.

A cooling curve represents the change in temperature of a substance over time as it loses heat and cools down. The curve typically shows a decrease in temperature as time progresses.

The internal energy of a substance refers to the total kinetic and potential energy of its particles. It includes the energy associated with their motion and position.

During the cooling process, the substance loses heat to its surroundings, resulting in a decrease in temperature. As temperature decreases, the average kinetic energy of the particles also decreases. This means that the overall internal energy of the substance decreases as well.

So, based on the understanding of cooling curves and internal energy, we can conclude that the internal energy of a substance does decrease as shown by a cooling curve.
