Heat is supplied to a diatomic gas at constant pressure. The ratio of DeltaQ : DeltaU : DeltaW is a) 5: 3: 2 b) 7: 5: 2 c) 2: 3: 5 d) 2: 5: 7

A cyclic process for an ideal monatomic gas (C_(v)=12.5Jmol^(-1)K^(-1) ) is represented in the figure. The temperature at 1, 2 and 3 are 300K, 600K and 455K , respectively. Compute the values of DeltaQ, DeltaU and DeltaW for each of the process. The process from 2 to 3 is adiabatic.

(A): If an ideal gas expands in vacuum in an insulated chamber, DeltaQ,DeltaU,DeltaW all are zero (R ): Temperature of gas remains constant

Correct relation for isothermal reversible expansion of an ideal gas is DeltaS = 0 DeltaG = - T DeltaS DeltaH != 0 DeltaU != 0
