is a measure of the average value of the kinetic energy of the molecules in random motion

the sum of the kinetic and potential energy of all the molecules in an object is

is the transfer of thermal energy from one object to another when the objects are at different temperatures.

when the particles in a material collide with neighboring particles

occurs when energy is transferred by electromagnetic waves.

thermal energy by the movement of atoms or molecules from one part of a material to another

any material that easily transfers thermal energy.

is the amount of thermal energy needed to raise the temperature

this increase in the temperature of a body of water caused by adding warmer water.
