If the absolute temperature of a gas is reduced to one half and the pressure is doubled, the volume of gas will be:
Correct answer: B. Decreased four times
- A. Increased four times
- B. Decreased four times
- C. Remained unchanged
- D. Reduced to one half
- E. Increased two times
Explanation
PV=nRT V=nRT/P If temperature is halved and pressure is doubled then V=n x R x 0.5T/2P = V=¼(nRT/P) Hence, volume is decreased four times.

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.
