According to boyle’s law, when the pressure on a gas increases at constant temperature, its volume
a. increases.
b. stays constant.
c. decreases.
d. increases, then decreases

The volume of the gas decreases when pressure on the gas increases.

Explanation:

Boyle's law is one of the laws of gases which relates volume and pressure of the gas.

According to this law, the pressure is inversely proportional to the volume of the gas at constant temperature.

Mathematically,

     (At constant temperature)

If the pressure on the gas increases, the volume of the gas decreases and vice-versa.

Hence, the volume of the gas decreases when pressure on the gas increases.
