Thermal conductivity - measure of how quickly energy is transferred through a material.

Convection - energetic particles move away from hotter to cooler regions.

Convection currents - the cycle of warm air rising and cool air sinks.

Lubrication - used to reduce the friction between objects' surfaces when they move.

Insulation - reduces the rate of energy transfer by heating.
