Conduction, Convection, & Radiation

Front

What is the process called when warm air rises and cool air sinks?

Back

Convection

Front

How does convection primarily transfer heat?

Back

Convection is the primary way heat travels through liquids and gases.

Front

What happens to thermal energy when two objects at different temperatures are in contact?

Back

Thermal energy passes from the warmer object to the cooler object.

Front

What is the definition of conduction?

Back

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

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

Can you give an example of radiation affecting temperature?

Back

A car’s inside temperature rises to over 100 degrees on a sunny day due to radiation.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in fluids (liquids and gases) through movement.

Front

What role does density play in convection currents?

Back

In convection currents, warmer, less dense fluid rises while cooler, denser fluid sinks.

Front

What is an example of conduction in everyday life?

Back

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

Front

How does the process of convection contribute to weather patterns?

Back

Convection helps distribute heat in the atmosphere, influencing wind and weather patterns.
