Internal energy of ideal gas

[Riya Sood 4G]

Is the internal energy of an ideal gas 0 at constant temperature?

[Jack Riley 4f]

the change in internal energy is 0 at constant temperature, however the internal energy itself is not necessarily 0 at constant temperature

[Michelle Xie 2B]

only delta U, or change in internal energy is 0.

[Anish Natarajan 4G]

There will always be some internal energy due to the movement of molecules in a system; however the change in internal energy will be 0

[Dina Marchenko 2J]

Why is the change in internal energy of an ideal gas 0 at constant temperature? What about a constant temperature and it being an ideal gas makes the internal energy not change?

[Leonardo Le Merle 1D]

They DO have internal energy, but there is no change in internal energy. Basically, because ideal gas are extremely non-reactive particles (already fully stable), they don't "see" each other at all. The average kinetic energy is nothing else than the temperature of the ideal gas, and if this is constant, there will be no change in U.

[Tanmay Singhal 1H]

the change is 0 but not the internal energy
