At constant pressure P the volume of a gas increases from V1 to V2 when Q amount of heat is removed from the system. What will happen to internal energy?

Increase by some unknown amount

Remain the same if Q = P(V1 V2)

Decrease by an amount P(V2 V1) Q

Decrease by an amount Q + P(V2 V1)

Increase by some unknown amount
