At constant temperature when the volume of the given mass of gas is doubled, its density becomes
Correct answer: D. Half
- A. Double
- B. One fourth
- C. Four times
- D. Half
Explanation
At constant temperature, the density of a gas is inversely proportional to its volume. Therefore, doubling the volume would halve the density.

About Ideal Gas Equation
The ideal gas equation, PV = nRT, relates pressure, volume, amount and absolute temperature when gas particles are assumed to have negligible volume and no intermolecular forces. Applications include finding molar mass, density or an unknown gas variable, with careful use of Kelvin temperature and consistent units, and comparison with real-gas behaviour.
