Vocab List -Thermal Energy Transfer Flashcards
Thermal Energy
The total Kinetic (motion) energy of tiny particles that make up matter. The faster the particles move, the warmer the matter becomes.
Temperature
The average kinetic energy of all the particles of a material; it is measured with a thermometer in degrees (usually Celcius or Fahrenheit).
Heat Transfer
The flow of thermal energy depending on the nature of the matter, the size of the sample, and the temperature of the environment.
Fahrenheit
Temperature scale, used largely in the USA, on which water freezes at 32F and water boils at 212F.
Celcius
A denoting scale of temperature of which water freezes at 0c and boils at 100c under standard conditions.
Kelvin
The SI base unit of thermodynamic temperature, equal in magnitude to the degree Celsius.
Conduction
Transfer of thermal energy by contact.
Convection
Transfer of thermal energy by currents.
Radiation
Any form of energy that radiates outward from a source.
Solid
A state of matter with definite volume and shape.
Liquid
A state of matter with a definite volume, but no definite shape.
Gas
A form of matter with indefinite shape and volume.
Conductor
A material that permits the flow of energy. (Electrical Conductor)(Thermal Conductor)
Insulator
Prevents the transfer of thermal energy.
Conservation of energy
A principle stating that energy cannot be created or destroyed, but can be altered from one form to another.
