HEAT FLOWS AND THERMAL EQUILIBRIUM

Front

What is heat?

Back

Heat is a form of energy that is transferred between systems or objects with different temperatures (from warmer to cooler).

Front

How does heat move?

Back

Heat moves from warm places to cooler places.

Front

What are the three methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is reached when two objects in contact have the same temperature and no heat flows between them.

Front

What happens to temperature during thermal equilibrium?

Back

The temperature of the warmer object decreases while the temperature of the cooler object increases until they are equal.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.
