Study Notes
Heat Transfer
- Heat moves from a higher temperature object to a lower temperature object.
- There are three main types of heat transfer: conduction, convection, and radiation.
- The method of heat transfer depends on the state of the material.
Conduction
- Conduction is heat transfer between touching objects.
- Heat energy passes between particles in the substance, from hotter areas to cooler.
- Metals are good conductors of heat.
Convection
- Convection is heat transfer in liquids and gases.
- Heated particles move, rising, while cooler particles fall to replace them.
- This creates convection currents.
Radiation
- Radiation is how heat travels through a vacuum (like space).
- Heat energy travels as electromagnetic waves.
- Radiation transfers heat and light energy to Earth.
