heat transfer Flashcards
law of Constitution of energy
energy cannot be made or destroyed just transformed (under normal conditions)
heat transfer
a method of heat flow.
heat
thermal energy that flows due to diffrent temperature.
conduction
heat transforms from solid objects.
radiation
Heat transfer due to packets of energy called photons that can travel through many substances, even empty space.
insurlater
. A material through which energy (electrical, thermal, or sound) cannot be easily transferred.
conductor
. A material through which energy (electrical, thermal, or sound) can be transferred.
temperature
The measure of the average speed of all particles.
thermal energy
The total energy of all particles in an object.
