Question

Under what conditions the change in the entrance of a system equals the heat supplied​

Answer 1

Answer:

If you heat the system at constant volume then the work done by the system is zero because system can't expand or contact therefore heating at constant volume is equal to the change in internal energy.

In second case if you heat the system at constant pressure means system's volume can change mean in this case system can do work then applied heat is equal to the sum of internal energy and the product of constant pressure and change in volume of the system.
