the degree or intensity of heat present in a substance or object
TEMPERATURE
the tendency of matter to change in shape, area, and volume in response to a change in temperature
THERMALEXPANSION
the lowest temperature that is theoretically possible
ABSOLUTEZERO
high temperature
HEAT
the internal energy of an object due to the kinetic energy of its atoms and/or molecules
THERMALENERGY
a measure of the ability of a material to transfer heat
THERMALCONDUCTOR
material of relatively low heat conductivity
THERMALINSULATOR
the transfer of heat (internal energy) by microscopic collisions of particles and movement of electrons within an object
THERMALCONDUCTION
the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity
CONVECTION
the emission of energy as electromagnetic waves or as moving subatomic particles
RADIATION
the heat required to raise the temperature of the unit mass of a given substance by a given amount
SPECIFICHEAT
the discharge of water or other liquid that is hot enough to harm wildlife into a natural body of water
THERMALPOLLUTION
