Physics 20 Lesson 27 Conservation of Energy
... The Law of Conservation of Energy states that the total amount of energy in a system remains constant. The energy may be transformed from one type to another, from kinetic to potential or kinetic to heat, but the total amount of energy is conserved. For example, imagine a skier starting from rest at ...

What is Energy?
... Chemical energy in the fuel (gas or oil) is released as heat in the boiler when it burns with air. Heat converts water in boiler tubes to steam, which is then used to drive a turbine that converts energy into mechanical energy. Mechanical energy drives an alternator to produce electrical energy. ...

Heat transfer physics
Heat transfer physics describes the kinetics of energy storage, transport, and transformation by principal energy carriers: phonons (lattice vibration waves), electrons, fluid particles, and photons. Heat is energy stored in temperature-dependent motion of particles including electrons, atomic nuclei, individual atoms, and molecules. Heat is transferred to and from matter by the principal energy carriers. The state of energy stored within matter, or transported by the carriers, is described by a combination of classical and quantum statistical mechanics. The energy is also transformed (converted) among various carriers.The heat transfer processes (or kinetics) are governed by the rates at which various related physical phenomena occur, such as (for example) the rate of particle collisions in classical mechanics. These various states and kinetics determine the heat transfer, i.e., the net rate of energy storage or transport. Governing these process from the atomic level (atom or molecule length scale) to macroscale are the laws of thermodynamics, including conservation of energy.
