Thermal Equilibrium

Front

What is the definition of convection?

Back

Convection is the transfer of heat by the movement of a fluid (liquid or gas) where hot fluid expands, becomes less dense, and rises, while cooler fluid becomes denser and sinks.

What is the primary method of heat transfer in solids?

Back

Conduction is the primary method of heat transfer in solids.

How is heat transferred from a hot burner to a pot?

Back

Heat is transferred from a hot burner to a pot primarily by conduction.

Front

What type of heat transfer occurs in fluids (liquids and gases)?

Back

Convection occurs in fluids (liquids and gases).

Where does conduction occur best?

Back

Conduction occurs best in solids.

What is the definition of conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

What is the definition of thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What is an example of convection in everyday life?

Back

An example of convection is the heating of water in a pot, where hot water rises to the top and cooler water sinks.

Front

What role does density play in convection?

Back

In convection, density differences caused by temperature variations drive the movement of fluid, with less dense (hotter) fluid rising and denser (cooler) fluid sinking.

What is the difference between conduction and convection?

Back

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