Question

A gas occupies $200mL$ at a pressure of $0.820$ bar at ${20}^{o}C$. How much volume will it occupy when it is subjected to external pressure of $1.025$ bar at the same temperature?

Answer 1

$200$ $ml$ at $0.820$ bar at $20°C$

$x$ $ml$ at $1.025$ bar at $20°C$

$P_1{V}_1=P_2{V}_{2}200\times 0.820=x\times 1.025x=160ml$
