Question

A sample of a gas occupies $10$ litre under a pressure of $1$ atmosphere. What will be its volume if the pressure is increased to $2$ atmosphere?

Assume that the temperature of the gas sample does not change.

Answer 1

Given $P_1=1atm$, $V_1=10L,P_2=2atm$.

Here, a temperature is constant.

Applying Boyle's law,

$P_1{V}_1=P_2{V}_2$

$⟹$$10\times 1=2\times V_2$

i.e $V_2=5L$
