Question

A sample of gas has a volume of 0.2 litres measured at 1 atm pressure and $0^{o}C$. At the same pressure, at ${273}^{o}C$, its volume will become:

• A. 0.1 litre
• B. 0.4 litre
• C. 0.8 litre
• D. 0.6 litre

Answer 1

The correct option is B 0.4 litre

According to Charles's law

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

$\frac{0.2}{273}=\frac{V}{546}$

$V=0.4litres$
