Page 2: Heat Transfer. Thermodynamics - The study of how heat moves Heat will transfer until both objects are in THERMAL EQUILIBRIUM This means they are both

Thermodynamics - The study of how heat moves

• Heat will transfer until both objects are in THERMAL EQUILIBRIUM

• This means they are both the SAME TEMPERATURE.

Page 3: Heat Transfer. Thermodynamics - The study of how heat moves Heat will transfer until both objects are in THERMAL EQUILIBRIUM This means they are both

Heat Transfer• Heat can be transferred in 3 ways

– Conduction– Convection– Radiation

• Heat flow depends on the temperature difference – flows from hot to cold

Heat Conduction• Conduction – is the transfer of

heat through materials by the direct contact of matter

Heat Conduction

Heat Conduction

When you heat a metal strip at one end, the heat travels to the other end. As you heat the metal, the particles vibrate, these vibrations make the adjacent particles vibrate, and so on and so on, the vibrations are passed along the metal and so is the heat.

Heat Convection• Convection – is the transfer of

heat by the motion of fluids (liquids and gases)

Convection Currents

Convection Currents• Much of Earth’s climate is regulated by

giant convection currents in the ocean

Heat Radiation• Radiation – is the transfer of

heat by electromagnetic waves – no medium
