Convection, Conduction, Radiation Practice

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer areas of a liquid or gas rise and cooler areas sink, creating a circulation pattern.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one without the movement of the material itself.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

How does heat transfer from a fire to a marshmallow?

Back

Heat from the fire is radiated to the marshmallow.

Front

In which direction does heat transfer occur?

Back

Heat transfers from an area of high temperature to an area of low temperature.

Front

What is an example of conduction?

Back

Thermal energy being transferred from a hot mug of cocoa to the table it is sitting on is an example of conduction.

Front

What is an example of convection?

Back

Movements of water in a pot, molten mantle in the earth's crust, and hot air rising in the atmosphere are examples of convection.

Front

What happens when the 2nd story of a house is warmer than the 1st floor?

Back

Heat transfer occurs through convection.

Front

What is the primary method of heat transfer in liquids and gases?

Back

Convection is the primary method of heat transfer in liquids and gases.

Front

What is the difference between conduction and convection?

Back

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