Temperature is a measure of the average kinetic energy of the particles in a substance, including gases. When the temperature of a gas increases, the energy supplied to the gas causes the molecules to move more rapidly. As the particles gain energy, their speed and, consequently, their kinetic energy increases. This relationship is pivotal in understanding the behavior of gases, particularly as described by the gas laws.

When gas is heated, the particles collide with each other and with the walls of their container more forcefully and frequently because they are moving faster. This increase in motion translates directly to an increase in the average kinetic energy of the gas particles. This concept is grounded in the kinetic theory of gases, which posits that temperature is proportional to the average kinetic energy of the particles.

This fundamental understanding of the relationship between temperature and kinetic energy is essential for various applications in physics, including thermodynamics and the behavior of gases under different conditions. As a result, the correct choice accurately reflects the direct impact of temperature changes on the kinetic energy of gas particles.
