Heat Transfer Unit 11: Forces & Energy

Thermodynamics The study of how heat moves

Heat Transfer Heat moves from HOT to COLD Insulators slow down heat transfer Conductors easily allow heat transfer

Heat Transfer Heat transfer continues until BOTH objects are in Thermal Equilibrium. This means that both objects are at the SAME TEMPERATURE!

Heat Transfer There are 3 types of Heat Transfer Conduction Convection Radiation

Heat Transfer Conduction - Heat transfer through objects that are touching each other Example: Metal spoon in hot pot

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 Transfer Convection - Heat transfer through matter by moving currents in liquids or gases Examples: Hot air rises, cold air falls creating wind in storms; currents in heated water.

Convection Currents

Convection Currents

Convection Currents Much of Earth’s climate is regulated by giant convection currents in the ocean

Heat Transfer Radiation - Heat transfer through electromagnetic waves. Examples: Sun warms the Earth; standing far from a fire but feeling the warmth
