ok so DELTA U = Q - W(adsbygoogle = window.adsbygoogle || []).push({});

Where U is internal energy, Q is heat transferred from or to the system and W is the work done BY the gas right?

I always mix up U and Q, the concepts. My teacher said U depends entirely on temperature, is this right??

Also, if Q =ncDELTA T, isnt Q also dependent on a change of temperature?

We saw that for an isotermic process, Q = W......WHY!?!?! If it is isotermic, isnt delta T = 0 , so that Q = is 0? Instead my teacher wrote that for an isotermic process, delta U is zero?

Can someone explain this?

Thanks a lot for reading and helping.
