detailed solution

Correct option is D

Ideal gas equation PV = μRT = (NNA)RT where N = Number of molecules, NA = Avagadro number∴ N1N2 = (P1P2)(V1V2)(T2T1) = (P2P)(VV4)(2TT) = 41

For one-mole ideal gas, a process follows the relation P=V2V2+V02P0, where P0 and V0 are constants. If the volume the gas changes from V0 to 2V0. What is the change in temperature?
