Question

Which one of the following options is the correct combination?

• A. $\left(II\right)\left(iv\right)\left(P\right)$
• B. $\left(III\right)\left(ii\right)\left(S\right)$
• C. $\left(II\right)\left(iv\right)\left(R\right)$
• D. $\left(IV\right)\left(ii\right)\left(S\right)$

Answer 1

The correct option is B $\left(III\right)\left(ii\right)\left(S\right)$

I: Work done by adiabatic process:

$W_{1-2}=\frac{(P_2{V}_2-P_1{V}_1}{\gamma -1})$

II: Work done by isobaric process:

$W_{1-2}=-P{V}_2+P{V}_1=P\Delta V$

III : Work done by isochoric Process :

$W_{1-2}=0$. As the volume is constant throughout the process.

IV: Work done by isothermal :

$W_{1-2}=-nRTln\frac{V_2}{V_1}$
