A sample of H2(g) expands adiabatically and reversibly from a state 1 where p1 = 200000Pa,V1 = 0.002m3 and T1 = 300K to a state 2 where V2 = 0.004m3.Assume the gas to behave as an ideal gas calculate the final temperature and its pressure.Use the constant value,Cp = 28.8 j/molK.Calculate n(moles of H2),change in internal energy,w and enthalpy change#### anyone to help me especially n and final temperature
