Thermal Equilibrium TEK 6.9B

Front

What is Convection?

Back

Transfer of thermal energy in a liquid or gas where the warmer substance rises and the cooler substance sinks, forming a current.

Front

In which direction does heat always travel?

Back

Heat always travels from hot to cold objects.

Front

What happens to a cold object placed in a warmer environment?

Back

The cold object will eventually reach the same temperature as the warmer environment.

Front

What is Thermal Equilibrium?

Back

A state where two objects in contact reach the same temperature and no heat flows between them.

Front

What is the process called when heat moves through direct contact?

Back

Conduction.

Front

What is Radiation in terms of heat transfer?

Back

Transfer of heat through electromagnetic waves without needing a medium.

Front

What happens when ice is placed in warm water?

Back

The heat from the water moves into the ice, causing the ice to melt and the water to cool.

Front

What is the main principle behind thermal energy transfer?

Back

Heat moves from areas of higher temperature to areas of lower temperature.

Front

What is an example of Convection in everyday life?

Back

Boiling water where hot water rises and cooler water sinks.

Front

What is the difference between Conduction and Convection?

Back

Conduction is heat transfer through direct contact, while convection involves the movement of fluids.
