Question

State True or False.

When a 200 ml gas, in a closed vessel, is heated to ${50}^{\circ }C$ from ${25}^{\circ }C$, the volume becomes doubled.

• A. True
• B. False

Answer 1

The correct option is A True

$PV=nRT$
As the vessel is closed it means pressure will remain constant. So if we halves the temperature volume becomes half.
$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
$\frac{200}{25}=\frac{V_2}{50}$
$\therefore V_2=400ml$

Thus the volume is doubled. The given statement is true.
