At constant volume the pressure of a given mass of a gas is directly proportional to its absolute temperature is known

The pressure of an ideal gas is directly proportional to

Temperature of a gas remains constant, the pressure of a given mass of a gas is inversely proportional to its volume. Then the law is

At constant pressure , the volume of fixed mass of an ideal gas is directly proportional to

Root mean square velocity of a gas is directly proportional to the absolute temperature of the gas.

Which law states that the volume of an ideal gas at constant pressure is directly proportional to the absolute temperature?

Assertion : The volume of a given mass of a gas at constant pressure is directly proportinal to its kelvin temperature. Reason : The pressure of a fixed mass of a gas at constant volume is directly proportinal to the kelvin temperature.
