1.1.13 Conduction of Heat

• Thermal conduction is the process where energy is transferred by vibrating particles in a substance.
• The vibrating particles transfer energy from their kinetic store to the kinetic store of neighbouring particles.
• The direction of energy transfer is always from hot to cold.
• The higher the thermal conductivity of a material, the higher the rate of energy transfer by conduction across the material.
• Materials with high thermal conductivity heat up faster than materials with low thermal conductivity.
