    Study Notes

    Heat Transfer

    • Heat transfer occurs from a body at a higher temperature to a body at a lower temperature.

    Conduction

    • A good conductor of heat is a material that can easily transfer heat energy, such as metals like copper and silver.

    Specific Heat Capacity

    • The amount of heat energy required to raise the temperature of 1 gram of a substance by 1°C is known as specific heat capacity.

    Radiation

    • Heat can be transferred through electromagnetic waves, a process known as radiation.

    Convection

    • Convection is the movement of heat from one place to another through the movement of fluids.
