Answer
A is true but R is false.
Explanation— Gases are often compared at Standard Temperature and Pressure (STP) to have a common reference point. Hence, converting volumes to STP (typically 0°C and 1 atm) is a standard procedure. Hence, the assertion (A) is true.
For a given mass of a gas, a change in one or more than one variable, i.e., pressure, volume and temperature, results in a change in the remaining variables. 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.
