Vedclass · Answer

(A) In the given $P-V$ diagram:$1$. Process $I$ is a vertical line,meaning volume $V$ is constant. This is an isochoric process. Thus,$I-c$.$2$. Process $IV$ is a horizontal line,meaning pressure $P$ is constant. This is an isobaric process. Thus,$IV-b$.$3$. Processes $II$ and $III$ are curves representing changes in both $P$ and $V$. Since $II$ connects the $300 \ K$ and $500 \ K$ isotherms and $III$ connects the $500 \ K$ and $700 \ K$ isotherms,they represent adiabatic processes (as they cross isotherms). Specifically,$II$ is adiabatic and $III$ is isothermal (or vice versa depending on the specific slope analysis). However,looking at the options,$I-c$ and $IV-b$ are fixed. Comparing with options,$I-c, II-a, III-d, IV-b$ fits the standard interpretation where $II$ is adiabatic and $III$ is isothermal. Therefore,the correct match is $I-c, II-a, III-d, IV-b$.

For the given $P-V$ diagram of a thermodynamic system,match the curves with their respective thermodynamic processes. ($P$ = Pressure and $V$ = Volume)

$III$ $c)$ Isochoric
$IV$ $d)$ Isothermal
