If both temperature and volume of a gas are doubled, the pressure:
Correct answer: B. Remain unchanged
- A. Cannot be predicted
- B. Remain unchanged
- C. Is reduced to 1⁄2
- D. Is doubled
Explanation
If both temperature and volume of a gas are doubled, the pressure will remain the same. This is because the ideal gas law states that: PV = nRT It means that pressure is directly proportional to temperature and inveresely proportional to volume which shows that if both temperature and volume of a gas are doubled, the pressure will remain the same.

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.
