Thermal energy — definition?
Total kinetic energy of particles in a substance.
Heat — transfer?
Energy transferred due to temperature difference.
Modes of heat transfer — types?
Conduction, convection, radiation.
Fourier’s law — describes?
Heat transfer rate depends on thermal conductivity, temperature gradient, area.
Latent heat — involved in?
Phase changes like fusion and vaporization.
Stefan-Boltzmann law — power radiated?
$P = \sigma e A T^4$.
Conduction — transfer method?
Transfer through direct contact.
