Thermal Energy, Heat

vocabulary for sections 1-3

temperature a measure of the average kinetic energy of the individual particles in matter
ferenheit scale the temerature scale on which water freezes at 32 degrees and boils at 212 degrees
celsius scale the temperature scale on which water freezes at 0 degrees and boils at 100 degrees
kelvin scale the temperature scale at which 0 is the temperature at which no more energy can be removed from matter
heat thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature
specific heat the amount of heat required to raise the temperature of 1 kilogram of material by 1 Kelvin
conduction the process when heat is transferred from one particle of matter to another without the movement of the matter
convection the transfer of heat by the movements of currents within a fluid
convection current a current caused by the rising of heated fluid and the sinking of cooled fluid
radiation the transfer of energy by electro-magnetic waves
conductor a material that conducts heat well
insulator a material that does not conduct heat well
state one of the 3 forms- solid, liquid, or gas in which most matter on Earth exists
change of state the physical change form one state of matter to another
melting the change of state from a solid to a liquid
freezing the change of state from a liquid to a solid
evaporation vaporization that takes place on the surface of a liquid
boiling vaporization that occurs below the surface of a liquid
absolute zero the temperature at which no more energy can be removed form matter
condensation a change from a gas state to a liquid state
thermal expansion the expanding of matter when it is heated
thermal energy the total potential and kinetic energy of the particles in an object
