For isothermal process, p V= constant. Therefore, p - V graph is a rectangular hyperbola. Since, T2>T1 ⇒ (p V) text at T2>(p V) text at T1 Thus, the graph given in option (a) correctly represents the given situation.

Q. Identity the graph (s) which correctly represents an isotherm at temperatures $T_{1}$ and $T_{2} (T_{2} > T_{1})$ .

For isothermal process, $p V =$ constant.
Therefore, $p$ - $V$ graph is a rectangular hyperbola.
Since, $T_{2} > T_{1}$
$\Rightarrow (p V)_{at T_{2}} > (p V)_{at T_{1}}$
Thus, the graph given in option (a) correctly represents the given situation.

Q. Identity the graph (s) which correctly represents an isotherm at temperatures T1​ and T2​(T2​>T1​).

For isothermal process, pV= constant. Therefore, p - V graph is a rectangular hyperbola. Since, T2​>T1​ ⇒(pV)at T2​​>(pV)at T1​​ Thus, the graph given in option (a) correctly represents the given situation.
