Question

A sample of gas has a volume of 0.2 lit measured at 1 atm pressure and 0°C. At the same pressure, but at 273°C its volume will become

(a) 0.1 litre

(b) 0.4 litre

(c) 0.8 litre

(d) 0.6 litre

Answer 1

Correct option is (b) 0.4 litre

According to Charles's law

\(\frac{V_1}{T_1} = \frac{V_2}{T_2}\)

\(\frac{0.2}{273} = \frac V{546}\)

\(V = 0.4 \) litres
