At what temperature, given mass of a gas that occupies a volume of 2 litres at N.T.P. will occupy a volume of 4 litres, if the pressure of the gas is kept constant ?
Correct answer: A. 273°C
- A. 273°C
- B. 273°K
- C. 100°C
- D. 200°C
Explanation
At constant pressure, Charles's law gives V/T = constant using absolute temperature. Doubling the volume from 2 to 4 L doubles 273 K to 546 K, which is 273°C.
