Question

Two moles of a monoatomic ideal gas undergoes a process AB as shown in the figure. Then find the work done during the process in joule. ___

• A. 0

Answer 1

The equation of the line is given by (slope = tan 45=1 and hence the line passes through the origin) $P=\left(\frac{P_0}{V_0}\right)T$
Using gas equation PV = nRT
$\therefore \frac{nRT}{V}\Rightarrow V=\frac{nR{T}_0}{P_0}=constW=pdv=0$
