SUMMARY

The discussion focuses on the relationship between internal energy, heat, and work in ideal gases, specifically using the equation Q = ΔU + W. Participants clarify that work is considered positive when the system performs work on the environment. The conversation also touches on identifying whether the process is positive, negative, or zero, emphasizing the importance of understanding these thermodynamic concepts in the context of ideal gases.

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

Your answers are correct. What kind of a cycle is it?
