Internal Energy

[Anthony Pluhar 1J]

Why at constant temperature does the change in internal energy (delta U) equal zero?

[Jaelyn Christian 2J]

Temperature is held constant, therefore the change in energy is zero (U=0). So, the heat absorbed by the gas equals the work done by the ideal gas on its surroundings.

Why at constant temperature does the change in internal energy (delta U) equal zero?

At constant temperature, the change in internal energy equals zero because the heat absorbed is equal to the work done. The formula is DeltaU= Q-W, so if Q and W were equal, it would be x-x, which is 0.

When temperature is constant, the change in U comes out to be 0.

Why at constant temperature does the change in internal energy (delta U) equal zero?

Internal energy consists of kinetic energy which is directly related to changes in temperature. An increase in temperature causes particles to move faster; therefore, there is an increase in kinetic energy.

Keeping this in mind, if temperatures stay constant, there will me no changes in particle movement and internal energy will stay constant.
