    Two moles of an ideal monoatomic gas undergo a cyclic process as shown in figure. The temperatures in different states are given as 6 T1=3 T2=2 T4=T3=2400 K6{\text{ }T}_{1}= 3{\text{ }T}_{2}= 2{\text{ }T}_{4}=T_{3}= 2400\text{ }K. The work done by the gas during the complete cycle is ( R=R = Universal gas constant)
