A cylindrical container of volume 44.8 liters is containing equal no. of moles (in integer no.) of an ideal monoatomic gas in two sections A and B separated by an adiabatic frictionless piston as shown in figure. The initial temperature and pressure of gas in both section is 27.3 K and 1 atm. Now gas in section ‘A’ is slowly heated till the volume of section B becomes (1/8)th of initial volume.
Given: R = 2 cal/mol-K, Cvm of monoatomic gas = 3/2 R At 1 atm & 0⁰C ideal gas occupy 22.4 liter.
Change in enthalpy for section A in k Cal
(A) 48.3
(B) 80.53
(C) 4.83
(D) 8.05
