Assertion : For an ideal gas, at constant temperature, the product of the pressure and volume is constant.
Reason : The mean square velocity of the molecules is inversely proportional to mass.

(A): For an ideal gas, at constant temperature, the product of the pressure and volume is a constant. (R): The mean square velocity of the molecules is inversely proportional to mass.

Statement I: For an ideal gas at constant temperatures the product of the pressure and the volume is constant. Statement II: The mean square velocity of the molecules is inversely proportional of mass.

At constant temperature, the product of pressure and volume of a given amount of a gas is constant. This is :

At constant temperature the product of pressure and volume of a given amount of a gas is constant. Ths is :

At constant temperature the product of pressure and volume of a given mass of gas is constant. What is this law called ?
