Understand the Kinetic Molecular Theory: This theory explains the behavior of gas molecules, stating that gas pressure is due to collisions of molecules with the walls of the container.

Analyze statement I: Increasing the amount of gas molecules increases the pressure because more molecules result in more collisions with the container walls, thus increasing the force exerted.

Analyze statement II: Decreasing the temperature of a gas typically decreases the pressure because the molecules move slower, resulting in less frequent and less forceful collisions, contrary to the statement.

Analyze statement III: Decreasing the volume of a gas increases pressure because the molecules have less space to move, leading to more frequent collisions with the container walls.

Evaluate the statements: Based on the analysis, statement III is true according to the Kinetic Molecular Theory, while statement I is partially true and statement II is false.
