If absolute temperature of the gas is doubled and pressure is increased 4 times, then the volume becomes
Correct answer: A. Half
- A. Half
- B. Double
- C. 4 times
- D. Unchanged
Explanation
From PV = nRT, the volume is V = nRT/P. Doubling the absolute temperature multiplies the volume by 2 and quadrupling the pressure divides it by 4, so the volume becomes 2/4, which is half its original value.

About Thermodynamics
Thermal equilibrium and heat explain how temperature and energy transfer are related, while molar specific heats describe the heat required by a gas at constant volume or constant pressure. The first law connects heat supplied, work done and change in internal energy, with sign conventions kept distinct from temperature changes.
