1.	n moles of an ideal gas is made to undergo the cycle 1-2-3-4-1 as shown in figure. Process 3-4 is a straight line. The gas temperatures in states 1,2 and 3 are T_1,T_2 and T_3 respectively. Temperature at 3 and 4 are equal. Determine the work done by the gas during the cycle.
Answer» SOLUTION :`1/2nR[(T_3)/(T_2)+(T_2)/(T_1)-2](T_2 -T_1)`
