KIP: Thermal Energy Transfer

By direct contact between objects

By movement of fluids

By electromagnetic waves

By chemical reactions

Conductors allow thermal energy to move quickly, while insulators do not.

Insulators allow thermal energy to move quickly, while conductors do not.

Both conductors and insulators allow thermal energy to move quickly.

Neither conductors nor insulators allow thermal energy to move.

Warmer, less-dense material rises and cooler, more-dense material sinks.

Cooler, less-dense material rises and warmer, more-dense material sinks.

Both warmer and cooler materials rise.

Both warmer and cooler materials sink.

Radiation requires direct contact between objects.

Radiation can transfer energy through empty space.

Radiation involves electromagnetic waves.

Radiation only occurs in solids.
