The temperature and number of moles of a gas are held constant. which of the following is true for the pressure of the gas?
a. it is inversely proportional to the volume of the gas.
b it is directly proportional to the volume of the gas.
c it is inversely proportional to the mass of the gas.
d it is equal to the mass of the gas.

Pressure is inversely proportional to the volume of gas.

Explanation:

According to Boyle's law,

The volume of given amount of gas is inversely proportional to the pressure applied on gas at constant volume and number of moles of gas.

Mathematical expression:

P ∝ 1/ V

P = K/V

PV = K

when volume is changed from V1 to V2 and pressure from P1 to P2 then expression will be.

P1V1 = K         P2V2 = K

P1V1 = P2V2
