Particle theory of matter states that matter consists of many very small particles (atoms or molecules) are in constant motion and are held together by attractive forces.
Heat - form of energy/thermal energy that flows between bodies or regions due to temperature difference.
Conduction - Direct contact of an object.
Temperature - measure of the average kinetic energy of the particles in a substance.
Normal Body Temperature - 37°C or 37.5°C
Boiling Point - 100°C
Freezing Point - 0°C
Conduction - transfer of heat from one substance to another by direct contact.
Insulator - Electricity is not allowed to transfer.
Thermal Conductors - materials that allow heat to be easily transferred.
Convection Current - cycle of a heated fluid that rises and sinks.
Radiation - Heat energy can also travel in empty space without contact between the heat source and heated object.
Best surface for reflecting radiation is shiny white.
Best surface for absorbing radiation is dull black.
