Energy Transfer and Thermal Properties P2

Vocabulary flashcards on energy transfer, thermal properties, and radiation.

Thermal Conductivity

Indicates how quickly energy is transmitted through a material by thermal conduction.

Thermal Insulator

A material with low thermal conductivity, leading to a lower rate of heat loss.

Specific Heat Capacity

The energy needed to raise the temperature of 1 kg of a substance by 1 °C.

Infrared Radiation

All objects emit and absorb it; hotter objects emit more. Good absorbers are also good emitters.

Greenhouse Gases

Gases that trap infrared radiation, increasing Earth's temperature.

Black Body

A theoretical object that absorbs 100% of radiation and is a perfect emitter.

Absorb

To take in energy or radiation.

Emit

To give out energy or radiation.

Electromagnetic Spectrum

The range of all types of electromagnetic radiation.

Thermal Energy Transfer

The transfer of heat due to differences in temperature.

Convection

The movement within a fluid that results from differences in density caused by temperature variations.

Conduction

The transfer of heat from one particle to another without the movement of the material itself.

Radiation

The transfer of energy by electromagnetic waves
