PS Ch. 6


Temperature A measure of the average kinetic energy of the particles in the object.
Thermal Energy The sum of kinetic and potential energy of all the particles in an object
Heat The thermal energy that flows something at a higher temperature to something at a lower temperature.
Specific Heat The amount of heat that is needed to raise the temperature of 1kg of some material of 1 C
Conduction The transfer of thermal energy by collisions between particles in matter
Convection The transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place
Radiation The transfer of energy by electromagnetic waves
Insulator A material in which heat flows slowly
Solar Collector An active solar heating system that absorb radiant energy from the Sun.
Thermodynamics Thermal energy, heat, and work are related, and the study of the relationship among them.
First law of the Thermodynamics The increase in thermal energy of a system equals the work done on the system plus the heat transferred to the system.
Second Law of thermodynamics It is impossible for heat to flow from a cool object to a warmer object unless work is done.
Heat engine A device that converts heat into work
Internal Combustion Engine Where fuel is burned inside the engine in chamber or cylinders(The heat engine in a car)
