Thermal energy is the movement of particles within matter and is found in the sun, magma, heated water and even the human body. Heat represents the transfer of thermal energy between matter. More »

Thermal energy is used to cook food, heat buildings and generate electricity. The joule, named after James Prescott Joule, is the unit by which thermal energy is measured. More »

Examples of thermal pollution include the ways in which air and water become hotter as a result of artificial stimuli. One example is a lake overheating because of a nearby factory. More »

Thermal energy is made by the movement of particles within an object or system. The thermal energy of an object, and thus the temperature of an object, increases as its molecules move more quickly. More » Science Physics Thermodynamics

Thermal energy is the energy that a system or object possesses due to the random movement of its particles. When more particles are present, there is more movement, which results in more thermal energy. More » Science Physics Thermodynamics

The kinetic theory of matter states that all phases of matter have free-moving particles. Heat is transferred when high-energy, free-moving particles collide with slower particles. A chain reaction of collisions causes h... More »

Heat conduction is the transfer of internal energy (microscopic kinetic and potential energy) from a region of higher temperature to one of lower temperature by the interaction of particles like atoms, molecules, ions or... More »
