Question

A container of fixed volume contains a gas at 27°C. To double the pressure of the gas, the temperature of the gas should be raised to °C.

Hint:

To double the pressure at constant volume, the temperature must be doubled in absolute terms (Kelvin scale).

Answer 1

Correct Answer: 327

Using the ideal gas law, \( P \propto T \) for a constant volume. If the initial temperature is 27°C (300 K) and the pressure is doubled, the temperature must be raised to 327°C (or 600 K) to achieve this. 
Thus, the correct answer is 327°C.
