What happens to the volume of a gas

inside a cylinder if the temperature

does not change but the pressure is

reduced?

a. The volume of the gas increases.

b. The volume of the gas stays the

same.

c. The volume of the gas decreases.

d. There is not enough information

to determine the answer.

The correct answer is a. The volume of the gas increases.

Explanation:

In this case, we apply Boyle Mariotte's Law: for a given gas mass at constant temperature, the pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa).

If the pressure reduced, the volume increases according to the formula: P1xV1 = P2xV2
