Which of the following will increase the volume of a gas?

O

A. Decreasing the temperature of the gas

O

B. Decreasing the pressure applied to the gas

O

C. Decreasing the number of gas molecules

O

D. Decreasing the size of the gas molecules

SUBN

B. Decreasing the pressure applied to the gas molecules

Explanation:

According to Boyle's Law, the pressure of the gas is inversely proportional to the volume of the gas. So, the option B is correctly implied to it.

Other values such as Temperature, Number of molecules are inversely proportional to the volume of the gas.

Size of the gas molecules is negligible as compared to volume.
