As temperature increases, the kinetic energy of particles also increases. This is because temperature is a measure of the average kinetic energy of the particles in a substance. When the temperature rises, the particles gain more thermal energy, which causes them to move faster and collide with each other more vigorously.

This relationship is underlined by the kinetic molecular theory, which states that the temperature of a substance is directly proportional to the average kinetic energy of its particles. Therefore, an increase in temperature will lead to a corresponding increase in the kinetic energy, reflecting that the particles are in a more energetic and dynamic state.

Understanding this concept is crucial in various scenarios, such as predicting how gases behave under varying temperatures, and it plays a significant role in phase changes, chemical reactions, and thermodynamic processes.
