    Study Notes

    Heat Energy

    • Heat Transfer Methods: Conduction, convection, radiation
    • Conduction: Transfer of heat between objects in direct contact
    • Convection: Transfer of heat in liquids or gases (through movement of fluids)
    • Radiation: Transfer of heat through empty space (e.g., sunlight)

    Heat Energy Examples

    • Campfire: Radiation
    • Air Fryer: Convection
    • Pan Boiling Water: Convection
    • Egg Frying: Conduction
    • Sunshine on Beach: Radiation
    • Ironing Clothing: Conduction

    Temperature

    • Temperature: Measure of average kinetic energy of particles in a substance
    • Example of fast moving particles (high temperature): Campfire
    • Thermal energy: The flow of heat energy.

    Materials

    • Conductor: Material that easily transfers heat (e.g., metal)
    • Insulator: Material that does not easily transfer heat (e.g., Styrofoam)

    Other Terms

    • Particles: Smallest pieces of matter
    • Heat: Transfer of thermal energy
    • Warm air travels to cooler air: Convection (process)
