Question

A certain mass of a gas occupies a volume of $2$ litre at STP. Keeping the pressure constant at what temperature would the gas occupy a volume of $4$ litre :

• A. ${546}^{\circ }C$
• B. ${273}^{\circ }C$
• C. ${100}^{\circ }C$
• D. ${50}^{\circ }C$

Answer 1

The correct option is B ${273}^{\circ }C$

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 ${}^{o}C$.
