Answer 1

Answer:

A diatomic gas is heated at constant pressure. lf 105 J of heat is given to the gas, find the change in internal energy of the gas.

Suppose the volume changes from V1 to V2 and the temperature changes from T1 to T2 .The heat supplied at Δ Q = Δ U + PΔ V = Δ U + nRΔ T = Δ U + 2ΔU/f
