### Internal energy of ideal gas

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

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

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

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

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?

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.

the change is 0 but not the internal energy
