Match the thermodynamic processes taking place in a system with the correct conditions. In the table :
Match the thermodynamic processes taking place in a system with the correct conditions. In the table : $\Delta Q$ is the heat supplied, $\Delta W$ is the work done and $\Delta U$ is change in internal energy of the system.
Correct Option: , 4
(4)
(I) Adiabatic process : No exchange of heat takes place with surroundings.
$\Rightarrow \Delta Q=0$
(II) Isothermal process : Temperature remains constant
$\therefore \Delta T=0 \Rightarrow \Delta U=\frac{f}{2} n R \Delta T \Rightarrow \Delta U=0$
No change in internal energy $[\Delta U=0]$.
(III) Isochoric process volume remains constant
$\Delta V=0 \Rightarrow W=\int P \cdot d V=0$
Hence work done is zero.
(IV) In isobaric process pressure remains constant.
$W=P \cdot \Delta V \neq 0$
$\Delta U=\frac{f}{2} n R \Delta T=\frac{f}{2}[P \Delta V] \neq 0$
$\therefore \Delta Q=n C_{p} \Delta T \neq 0$
