    Study Notes

    Temperature Conversions

    • Kelvin to Fahrenheit: formula and conversion method
    • Kelvin to Celsius: not applicable, as Kelvin is an absolute temperature scale
    • Celsius to Fahrenheit: formula and conversion method
    • Fahrenheit to Celsius: formula and conversion method

    Heat Transfer Modes

    • Conduction: transfer of heat energy through direct contact between particles
    • Convection: transfer of heat energy through the movement of fluids
    • Radiation: transfer of heat energy through electromagnetic waves
    • Seabreeze: wind that blows from sea to land, cooling the air
    • Land breeze: wind that blows from land to sea, warming the air

    Thermal Concepts

    • Thermo flask: vacuum-insulated container that minimizes heat transfer
    • Construction: importance of insulation and thermal bridges
    • Working: thermal principles in the design of buildings and devices
    • Thermal expansion: change in size or volume of a substance in response to temperature changes
