Question 107 of 190

In an Isothermal change, the change in pressure and volume of a gas can be represented for three different temperature; ${T}_{3}\gt {T}_{2}\gt {T}_{1}$ as:

ABCD

Show answer and solution▾

Answer: (D)

In case of isothermal process, pressure vs volume graph is a rectangular hyperbola.
The graph of the isothermal process shifts away from the origin as the temperature of the process is increased. Thus, the curve away from the origin ${T}_{3}$ have the highest temperature whereas the curve closer to the origin ${T}_{1}$ have the lowest temperature.
Here, the dotted line shows the isobaric line that implies ${T}_{3}\gt {T}_{2}\gt {T}_{1}$ as $T=\dfrac{PV}{nR}$.
