Question

on reducing the volume of a gas at a constant temperature the pressure of a gas is increased why​

Answer 1

Answer:

On reducing the volume of the gas at constant temperature, the pressure of the gas increases. ... On reducing the volume, the space for the given number of molecules of the gas decreases, i.e. No. of molecules collide with the walls of the vessel per second and hence a large momentum is transferred to the walls per second.

Answer 2

Answer:

On reducing the volume the space for the given number of molecules of the gas decreases i.e., number of molecules per unit volume increases. As a result of which more molecules collide with the walls of the vessel per second and hence a large momentum is transferred to the walls per second due to which the pressure of the gas increases.
