Here's my problem:

300 calories of heat are added to a gas as the internal energy of the gas increases by 500 calories. The described thermodynamic process is best described as?

My guess is that the process is isothermal b/c work is being done in the system.

Since temperature is usually the measure of internal energy, it's unlikely that the internal energy increased without the temperature being changed. So that's probably not an isothermal process.

if that's the case then maybe it's isovolumetric b/c adiabatic can't have heat flow into or out of the system. any other ideas?

In what form is the 200 calories of energy added to the gas (since it is not in the form of heat)? What does that tell you about what happens to the volume of the gas?

What makes you think this is a choice between adiabatic, isovolumetric and isothermal?

It's a homework question and the answers are adiabatic, isovolumetric, isothermal or none. as for your other question about the other 200 calories, I have no clue. but I would think that the volume would stay the same. is that wrong?
