A system undergoes a two-step process. In the first step, the internal energy of the system increases by 368 J when 144 J of work is done on the system. In the second step, the internal energy of the system increases by 24 J when 248 J of work is done on the system.

(a) For the overall process, what is the heat?
J

(b) What type of process is the overall process?
Isobaric
Isochoric
Isothermal
Adiabatic

I'm thinking owuld add the levels of heat, but I'm not sure of what formula to used and I think the process would be Isochronic
