Question

The cyclic process for 1 mole of an ideal gas is shown in the V-T diagram. The work done in AB, BC and CA respectively is

A. (a) 0, `RT_(2)In|V_2/V_1|,R(T_1-T_2)`
B. (b) `R(T_1-T_2),0,RT_(1)In|V_1/V_2|`
C. (c) `0,RT_(1)In|V_1/V_2|,R(T_1-T_2)`
D. (d) 0,RT_(2)In|V_2/V_1|,R(T_2-T_1)`

Answer 1

Correct Answer - A
For AB V=constant
`therefore W=0`
For BC `W=nRT_(2)In(V_f/V_i)`
`=RT_2In(V_2/V_1)`
For CA `VpropT`
`:.` p=constant
`W=nRDeltaT`
`=R(T_1-T_2)`
