conduction + confection + radiation

when does conduction mainly occur

solids

define conduction

when particles in solid begins to vibrate due to heat, then they gain kinetic energy. They hit other particals, then they move gaining kinetic energy. Passing on the energy all the way to the last particle in the solid.

where does convection happen

in liquid and gasses only

define convection

when particals in liquid or gas is heated. Then the heated particles gain energy, making them go up. Then soon they Cool and go back down creating a cycle.

define radiation

when wave are transferred in infrared waves.
