It is the the ratio of reflected power to total incident power
It is a perfect emitter, absorber, and radiator
It is the radiation emitted from a black body
It is the transfer of thermal energy via direct collisions between molecules, thus passing kinetic energy from one molecule to another
It is the movement of thermal energy in a fluid
The cyclical movement of expanding and rising hot and less dense fluid and the condensation and sinking of cold and denser fluid
It is the ratio of emission intensity of the object to the emission intensity of a black body
It is the total kinetic energy of all particles in an object

It is the emission of electromagnetic waves from an object
The measure of how much energy a unit mass of a substance takes to be raised by 1K/1°C
It is the energy absorbed or released by a kg of a substance during a phase change
It is the energy absorbed by a kg of substance when it changes from solid to liquid
It is the energy absorbed by a kg of substance when it changes from liquid to gas
It is the average kinetic energy of an object's particles
It is the energy required to raise an object's temperature by 1 K
It is a material that is able to conduct thermal energy well
It is the movement of thermal energy from a hot object to a cold object
It is the state at which two objects are at the same temperature
It is the state of absorbing power at the rate of emission to maintain a constant temperature
It is a material that is not able to conduct thermal energy well
