JEE Mains · Physics · STD 11 - 12 . kinetic theory of gases
For three low density gases \(A, B, C\) pressure versus temperature graphs are plotted while keeping them at constant volume, as shown in the figure. The temperature corresponding to the point ' \(K\) ' is \(...........\,{}^{\circ}\,C\)
- A \(-273\)
- B \(-100\)
- C \(-373\)
- D \(-40\)
Answer & Solution
Correct Answer
(A) \(-273\)
Step-by-step Solution
Detailed explanation
For isochoric process \(\frac{ P }{ T }= n \frac{ R }{ V }= constan t\) \(P =\frac{ nR }{ V }( t +273)\) If \(P =0 \Rightarrow t =-273^{\circ}\,C\)
