Conduction • Convection • Radiation • Thermal Insulation
Heat is the transfer of thermal energy due to a temperature difference.
Heat transfer through direct contact between particles.
Example: A metal spoon heating up in hot soup
Heat transfer through the movement of fluids (liquids or gases).
Example: Boiling water or warm air rising in a room
Heat transfer by electromagnetic waves.
Example: Heat from the Sun reaching Earth
Materials that slow down heat transfer.
Examples: Wool jumpers, double-glazed windows, thermos flasks
