TermDefinition
Temperature Measure of the average kinetic energy of all the particles in an object.
Thermal Energy Sum of the kinetic and potential energy of the particles in an object; is transferred by conduction, convection, and radiation.
Heat Thermal energy that flows from a warmer material to a cooler material.
Specific Heat Amount of thermal energy needed to raise the temperature of 1 kg of a material.
Conduction Transfer of thermal energy by collisions between particles in matter at a higher temperature and particles in matter at a lower temperature.
Convection Transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from one place to another.
Radiation Transfer of thermal energy by electromagnetic waves.
Insulator Material in which electrons are not able to move easily.
Solar Collector Device used in an active solar heating system that absorbs radiant energy from the sun.
Thermodynamics Study of the relationship between thermal energy, heat and work.
First Law of Thermodynamics States that the increase in thermal energy of a system equals the work done on the system plus the heat added to the system.
Second Law of Thermodynamics States that it is impossible for heat to flow from a cool object to a warmer object unless work is done.
Heat Engine Device that converts thermal energy into work.
Internal Combustion Engine Heat engine that burns fuel inside the engine in chambers or cylinders.
