9 please help Rank in order from largest to smallest the amo

Rank in order, from largest to smallest, the amount of work (W_s)_1 to (W_s)_4 done by the gas in each of these cycles.

Solution

>> As, Work Done is Area Under P - V Curve.

>> Fig 1...

Area = 4*1 = 4 unit²

>> Fig 2 .....

Area = 1*4 = 4 unit²

>> Fig 3

Area = (1/2)*4*4 = 8 unit²

>> Fig 4

Area = (1/2)*1*4 = 2 unit²

>>So, Work Done in each process according to order :-

W₃ > W₁ = W₂ > W₄
