If we decrease temperature of a gas by 2 times, its volume will:
Correct answer: C. Decrease by 2 times
- A. Increase by 4 times
- B. Decrease by 4 times
- C. Decrease by 2 times
- D. Increase by 2 times
Explanation
According to Charles's Law, which describes the relationship between the volume and temperature of a gas, if we decrease the temperature of a gas by 2 times (halve the temperature), its volume will decrease by 2 times as well.Therefore, the correct answer is Decrease by 2 times.

About Gases
Gas behaviour is explained through the kinetic molecular theory and the relationships among pressure, volume and temperature. Work includes STP, Boyle's and Charles's laws, absolute zero, the ideal gas equation, and the distinction between ideal and real gases, especially the effects of intermolecular forces and molecular volume.
