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.


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.


A 10,000 BTU air conditioner refers to the size of the air conditioning unit and the amount of area it can cool, which is approximately 450 square feet. BTU is the standard measurement of energy used in the HVAC industry to refer to the size rating of an AC unit.


British Thermal Unit ratings are units of measure used to determine the heat of combustion of firewood. These numbers are a rough comparison of different types of firewood and depend on the species of tree, its burn and the season.


Thermal energy is used to describe energy in a heated form. Thermal energy is transferred in three different ways: radiation, conduction and convection.


A thermal power plant uses water to generate power. Fuel heats up the water to generate steam to create the electricity.


Solar thermal panels harness energy from the sun to energize homes and commercial buildings, according to Solar Systems USA. How Stuff Works mentions that geothermal energy is created by tapping into hot water or steam under the Earth to generate heat.


The best thermal insulators include aerogel, fiberglass, mineral wool, polystyrene, polyurethane foam and cellulose. Other effective insulators include cotton, straw and animal wool. Each material excels in separate applications and environments.


Thermal insulation can be defined as the material or a combination of materials that retard the transfer of heat. Heat may be transmitted between materials by the process of convection, conduction or radiation. Insulators reduce the flow of heat.


To be a good thermal insulator, a material must be resistant to the conduction, convection and radiation of heat. A good insulator is made from an opaque, nonmetallic material without a crystalline structure, and its insulating properties may be enhanced by creating small air pockets inside its stru
