B.1 Flashcards 2

Front

Change of phase

Back

Occurs when a substance changes from one state (solid, liquid, or gas) to another at a constant temperature.

Front

Specific latent heat

Back

The amount of energy required to change the phase of 1 kg of a substance at constant temperature.

Front

Conduction

Back

Transfer of thermal energy due to collisions between particles, best in solids.

Front

Best conductors of thermal energy

Back

Metals, because they have free electrons that transfer thermal energy.

Front

Factors affecting conduction rate

Back

Thermal conductivity, cross-sectional area, length, and temperature difference.

Front

Convection

Back

Transfer of thermal energy due to mass movement of particles, best in liquids and gases.

Front

Thermal radiation

Back

Transfer of energy by electromagnetic waves, emitting infrared radiation.

Front

Best emitters of infrared radiation

Back

Black, matt surfaces.

Front

Best reflectors of infrared radiation

Back

Light-colored, shiny surfaces.

Front

Phase change temperature

Back

Occurs at a constant temperature as energy increases potential energy between particles.
