Celsius scale most common temperature scale outside the US; the preferred temperature scale of scientists
absolute zero the temperature at which no more energy can be removed from matter
heat thermal energy moving from a warmer object to a cooler object
specific heat the amount of energy required to raise the temperature of 1 kg of a substance by 1 degree kelvin
conduction the transfer of heat from one particle of matter to another particle
convection the transfer of heat by the movement of currents through a fluid
convection current a circular motion resulting from the rising of a heated fluid and the sinking of a cooled fluid
radiation the transfer of energy by electromagnetic waves through space
conductor a material that conducts heat easily
insulator a material that does not conduct heat well
