Question

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 :

• A. $-373^{\circ} C$
• B. $-40^{\circ} C$
• C. $-100^{\circ} C$
• D. $-273^{\circ} C$

Answer 1

Answer: (D)

$-273^{\circ} C$

Answer 2

For isochoric process
$\frac{P}{T}​=n\frac{R}{V}​= constan\; t$

$P=\frac{nR}{V}​(t+273)$

If $P=0⇒t=−273\degree C$

The Correct Option is (D): $-273\degree C$
