Correct option is C
As it is a constant pressure process volume becomes double temperature also becomes double so increase in temperature is T0.given U = 2PV; ∆U = 2P0V0Work done at constant pressure P02V0-V0 =P0V0dQ = dU + dW = 3P0V0Similar Questions
At the middle of the mercury barometer tube there is a little column of air with the length and there is vacuum at the top as shown. Under the normal atmospheric pressure and the temperature of 300 kelvin, l0 = 10cm Neglect expansion of the tube. The length of the air column if the temperature rises to 330 kelvin in equilibrium will be
