science 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 material; is measured with a thermometer in degrees (usually Celsius 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
The temperature scale mostly used in the U.S.
Celcius
The temperature scale mostly used in the U.K.
Kelvin
The temperature scale mostly used in science
Conduction
Transfer of thermal energy by contact
Convection
Transfer of thermal energy by currents
Radiation
Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium
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 conductor is an object or type of material that allows the flow of charge in one or more directions. Materials made of metal are common electrical conductors.
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.
