conduction: transmission of heat through direct contact
convection: transmission of heat requiring the movement of liquids and gases
radiation: transmission heat through waves; no contact necessary.
radiant energy: heat energy rays involved in the process of radiation
critical temperature: temperature at which the molecules of a substance will change their state
melting: the process by which a substance changes from a solid to a liquid
evaporation: the process by which a substance changes from a liquid to a gas
condensation: the process by which a substance releases energy to change from a gas to a liquid
reasonable temperature: temperature that may be conveniently obtained in a lab or industry.
latent heat of fusion: amount of heat energy required to change a unit of mass of a solid to the liquid state without a change in temperature
volatile liquid: a liquid that evaporates quickly at a low temperature
refrigerant: volatile liquid in coils of the evaporator in a refrigerator
evaporator: coils of pipes that surround freezer in a refrigerator
fuel: substance that contains stored chemical energy that can be released
combustion: process by which energy is released through a chemical combination and reaction.
ignition point: temperature at which combustion occurs between fuel and oxygen.
fuel oil: substance that remains as a liquid after crude petroleum is distilled
flash point: lowest temperature at which the oil gives off a vapor that can be ignited.
heating value: heat energy that can be developed from the complete burning of a unit mass of fuel.
