Let's explore kinetic energy and thermal energy and how they relate to temperature changes in substances.

• Kinetic Energy is the energy an object has because of its motion. On a microscopic level, it refers to the energy of particles moving or vibrating.
• Thermal Energy is the total kinetic energy of all the particles in a substance due to their random motion; it reflects how hot the substance is.

When the temperature of a substance increases, its particles move faster, so both the kinetic energy of individual particles and the overall thermal energy of the substance increase. How familiar are you with these concepts? This will help me tailor the explanation just right for you.
