Question

A certain sample of gas has a volume of 0.2 litre measured at 1 atm pressure and ${}^{\circ }C$. At the same pressure but at ${273}^{\circ }$C, its volume will be

• A. 0.4 litres
• B. 0.8 litres
• C. 27.8 litres
• D. 55.6 litres

Answer 1

The correct option is A

0.4 litres

$\frac{V_1}{V_2}=\frac{T_1}{T_2}\because V_2=\frac{T_2}{T_1}{V}_1=\frac{{546}^{\circ }K}{{273}^{\circ }K}\times 0.2L=0.4L$
