Energy transfer by heating
Key Words
Conduction - the process where vibrating particles transfer energy to neighbouring particles.
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.
