Question

A certain mass of a gas occupies a volume of 2 litres at S.T.P. Keeping the pressure constant, at what temperature would the gas occupy a volume of 4 litres?

(a) 546°C

(b) 273°C

(c) 100°C

(d) 50°C

Answer 1

Correct option is (b) 273°C

The volume is directly proportional to temperature.

When volume is doubled from 2 L to 4 L, the temperature is also doubled from 273 K to 546 K which corresponds to 273°C.
