NEET Physics Thermodynamics Questions Solved


If the ratio of specific heat of a gas at constant pressure to that at constant volume is γ, the change in internal energy of a mass of gas, when the volume changes from V to 2V constant pressure p, is 

(1) R/(γ1)

(2) pV

(3) pV/(γ1)

(4) γpV/(γ1)

(3) ΔU=μCVΔT=nRγ1ΔT

ΔU=PΔV(γ1)=P(2VV)γ1=PV(γ1)
