What happens to the pressure of a gas in a closed container if you double its volume while its temperature is held constant?

This question lacks options, the options are:

A) It would increase by a factor of four.

B) It would decrease by a factor of four.

C) It would be halved.

D) It would be doubled.

E) It would not change.

The answer is C

Explanation:

The relationship between the pressure and volume has been explained by BOYLE in his law. Boyle's law states that, at a constant temperature, the volume is inversely proportional to the pressure of a gas. This means that as the VOLUME INCREASES, the PRESSURE DECREASES and vice versa.

P ∝ 1/V or V ∝ 1/P

Hence, based on this explanation, when the volume of a gas in a closed container is doubleb, its pressure will be reduced by half i.e. 1/2. In other words, the pressure will be HALVED.

b would be the answer
