At constant temperature when the volume of the given mass of gas is doubled its density becomes:doubled,temperature,At a
Correct answer: D. half
- A. double
- B. one fourth
- C. four times
- D. half
Explanation
Density is mass divided by volume and the mass of gas is fixed, so doubling the volume at constant temperature halves the density.

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.
