Assertion (A): When stating the volume of a gas, the pressure and temperature should also be given.
Reason (R): The volume of a gas is inversely proportional to temperature and directly proportional to pressure.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.

Answer
A is true but R is false
Explanation— The change in one or more than one variable, i.e., pressure, volume and temperature, results in a change in the remaining variables. So, when stating the volume of a gas, the pressure and temperature should also be given. Hence, the assertion (A) is true.
The volume of a gas is directly proportional to temperature and inversly proportional to pressure. Hence, the reason (R) is false.

Assertion (A): Gases exert pressure on the walls of the container they are kept in.
Reason (R): Gas molecules have a large kinetic energy. They strike the walls of the container in which they are kept with a certain force. The force per unit area is responsible for the pressure of the gas.
