Vedclass · Answer

(D) In a $P-V$ diagram:$1$. An isobaric process is represented by a horizontal line where pressure is constant. Thus,isobaric $\rightarrow$ process $a$.$2$. An isochoric process is represented by a vertical line where volume is constant. Thus,isochoric $\rightarrow$ process $d$.$3$. For isothermal and adiabatic processes,the slope of the adiabatic curve is $\gamma$ times the slope of the isothermal curve,where $\gamma > 1$. Therefore,the adiabatic curve is steeper than the isothermal curve.$4$. Comparing curves $b$ and $c$,curve $c$ is steeper than curve $b$. Hence,isothermal $\rightarrow$ process $b$ and adiabatic $\rightarrow$ process $c$.$5$. The correct order is: isochoric $(d)$,isobaric $(a)$,isothermal $(b)$,adiabatic $(c)$.$6$. Therefore,the correct sequence is $d, a, b, c$.

The given diagram shows four processes,i.e.,isochoric,isobaric,isothermal,and adiabatic. The correct assignment of the processes,in the same order,is given by
