heat transfer
A methood which heat flows.
heat
Thermal energy that flows due to a difference in temperature.
conduction
Heat transfer within or between solid objects.
convection
Heat transfer into or out of fluids.
radiation
Heat transfer due to packets of energy called photons that can travel through many substances, even empty space.
insulator
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
