Question

If II and III are three isotherms respectively at temperatures $T_{2},T_{2}$ and $T_{3}$ then temperature will be in order

• A. $T _{1}= T _{2}= T _{3}$
• B. $T _{1}> T _{2}= T _{3}$
• C. $T _{1}> T _{2}> T _{3}$
• D. $T _{1}< T _{2}< T _{3}$

Answer 1

Answer: (C)

Draw a line at constant pressure parallel to volume-axis.
Take volume corresponding to each temperature.
From volume axis $V_{1} > V_{2} > V_{3}$
Thus, $T_{1} >T_{2} >T_{3}$
