DescriptionThermal energy can refer to several distinct thermodynamic quantities, such as the internal energy of a system; heat or sensible heat, which are defined as types of transfer of energy; or for the characteristic energy of a degree of freedom in a thermal system

the energy released during nuclear fission or fusion, especially when used to generate electricity.

power derived from the utilization of physical or chemical resources, especially to provide light and heat or to work machines.

Conduct the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

the emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.

Thermal expansion is the tendency of matter to change its shape, area, and volume in response to a change in temperature. Temperature is a monotonic function of the average molecular kinetic energy of a substance. When a substance is heated, the kinetic energy of its molecules increases.

Joule the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.

the law of conservation of energy states that the total energy of an isolated system remains constant; it is said to be conserved over time.
