conduction
Particles bump into one another to transfer hear energy. Heat is transferred through solids.
convection
Hot air rises and cold air falls. Heat is transferred through fluids. Creates a convection current.
radiation
heat is transferred as a wave. Heat can be transferred through empty space (no matter).
convection currents
movement of energy from one place to another
example of conduction
the heat from a stovetop transferring to a pot filled with water
example of convection
Sea breeze or land breeze caused by a difference in pressure.
example of radiation
5G technology, cell phones, cell phone towers and antennas.
1 conduction (fire)
energy transferred by direct contact
2 convection
energy transferred by molecular motion
3 radiation
energy transferred by electromagnetic waves
