# PV Diagram

Can some one check my work, I'm not sure if I am understanding how internal energy heat and work are related.

Work is defined to be positive if the system does work on the environment.

Q=$\Delta U$ +W

I am showing if the process is positive, negative or 0.

Also this is suppose to be an ideal gas
