Question

The pressure of $2L$ of $O_2$ gas is doubled when its temperature is increased from 300 K to 600 K. Find the final volume of the gas.

• A. 4 litres
• B. 20 litres
• C. 40 litres
• D. 2 litres

Answer 1

The correct option is D

2 litres

Given,
Intial volume $V_1=2L$
Intial temperature $T_1=300K$
Final temperature $T_2=600K$
Using Ideal gas equation
$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$
$\frac{P_1\times 2}{300}=\frac{2P_1\times V_2}{600}$

$V_2=2litres$
