Question

Relationship between internal energy heat and work done.​

Answer 1

here is your answer

⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️

Since the system has constant volume (ΔV=0) the term -PΔV=0 and work is equal to zero. Thus, in the equation ΔU=q+w w=0 and ΔU=q. The internal energy is equal to the heat of the system. The surrounding heatincreases, so the heat of the system decreases because heat is not created nor destroyed.


hope it works ✌
