Which type of kinetic energy is associated with temperature?

Thermal energy is the correct choice because it directly relates to the kinetic energy of particles within a substance. Temperature measures the average kinetic energy of the particles in a material; when the temperature increases, the particles move faster, reflecting an increase in thermal energy. This concept is rooted in the kinetic theory of matter, which posits that all matter is made of particles that are in constant motion. As the motion of the particles increases due to added heat, the thermal energy also increases.

Other forms of energy mentioned, like sound, electrical, and radiant energy, do not directly represent the kinetic energy tied to temperature. Sound energy is associated with the vibration of particles, electrical energy pertains to the movement of charged particles, and radiant energy involves electromagnetic radiation, none of which are measured in the same way or are fundamentally the same as thermal energy related to temperature.
