Heat Transfer Notes

Thermal energy is the total kinetic energy of particles, while heat is energy transferred due to temperature difference.

Thermal energy is energy transferred from hot to cold, while heat is the total kinetic energy of particles.

Thermal energy and heat are both the same and refer to the movement of particles.

Thermal energy is only found in solids, while heat is found in liquids and gases.

Conduction is the transfer of heat by direct contact.

Convection is the transfer of heat by the movement of a liquid or gas.

Radiation is the transfer of heat in the form of waves.
