Thermal Energy: the sum of the kinetic and potential energy of all the particles in an object.

Heat: is the thermal energy that flows from something at a higer temperature tosomething at a lower temperature.

Temperature (SI unit): is a measure of the average kinetic energy of the particles in the object.

Specific heat: the amount of heat that is needed toraise the temperature of 1 kg of some material by 1*C.

Conduction: is the transfer of thermal energy by collisions between particles in matter. Conduction occurs because particles inmatter are in constant motion.

Convection: is the transfer of thermal energy in a fluid by the movement of warmer and cooler fluid from place to place.

Radiation: is the transferof energy by electromagnetic waves.

Insulators: is a material in which heat flows slowly.
