Thermal Energy

temperature the average amount of kinetic energy in the particles of a substance
thermal energy the total amount of energy in the particles of a substance
heat thermal energy that is moving
conduction thermal energy is transferred between two touching objects or substances
convection movement of thermal energy through currents in a fluid such as a gas or liquid
radiation movement of thermal energy in the form of waves
conductor a substance that allows thermal energy to pass into or out of it easily
insulator a substance that does not conduct heat well
specific heat the amount of energy required to raise the temperature of one kilogram of a substance by one Kelvin
vaporization liquid state of matter becomes a gas
evaporation liquid state of matter becomes a gas at the surface of a liquid
sublimation solid state of matter skips the liquid phase to become a gas
condensation gas state of matter looses thermal energy to become a liquid
thermal expansion as thermal energy increases, the particles of a substance spread out causing this to happen
bimetallic strips two different metals are joined together, when heated one expands faster than the other causing the piece of metal to bend in a curve
combustion the process of burning a fuel
external combustion engine burns fuel outside of the engine
internal combustion engine burns fuel inside the engine
intake, compression, power, exhaust the "4-stroke engine cycle" that takes place in some internal combustion engines
heat movers use an outside energy source to transfer thermal energy from cooler to warmer areas
