Step-by-step explanation:
According to ideal gas equation, PV = nRT.
When more is the concentration of particles of a gas it means more number of molecules or more number of moles are present.
As pressure is directly proportional to number of moles of a gas. Therefore, when there are more number of moles of a gas then there will be more number of collisions.
As a result, there will be increase in pressure.
Thus, we can conclude that the game pressure of a gas is directly related to its concentration of particles.
