Heat Transfer and Air Masses

Front

Temperature is also known as "heat" energy or "thermal" energy.

Back

Thermal energy is the energy that comes from the temperature of matter.

Front

Conduction: Energy moves between two substances in contact.

Back

Conduction is the process of heat transfer through direct contact.

Front

Convection: Energy moves through a fluid material.

Back

Convection is the transfer of heat by the movement of fluids.

Front

Convection example: Water boiling in a pot on the stovetop.

Back

This shows how heat is transferred through the movement of water.

Front

Radiation: Energy travels through waves from one place to another.

Back

Radiation does not require a medium to transfer energy.

Front

Radiation example: Rays from the sun heating up sand on the beach.

Back

This illustrates how energy travels through space.

Front

Characteristics of cool air: Calm, cool, collected, contracts, more dense.

Back

Cool air is denser and tends to sink.

Front

Warm air has lower pressure.

Back

This is due to the expansion of warm air.

Front

Cool air has higher pressure.

Back

Cool air is denser and exerts more pressure.

Front

Maritime tropical air mass forms over water near the equator.

Back

This air mass is typically warm and moist.
