Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through liquids and gases, where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight or heat from a lamp.

Front

Give an example of conduction.

Back

An ice cube melting in a person's hand is an example of conduction.

Give an example of convection.

Back

Warm air rising and cool air sinking is an example of convection.

Give an example of radiation.

Back

The heat from the sun warming the Earth is an example of radiation.

Front

What happens to air when it is heated?

Back

When air is heated, it expands, becomes less dense, and rises.

Front

What happens to air when it cools?

Back

When air cools, it becomes denser and sinks.

Front

What is the primary way heat travels through liquids and gases?

Back

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

Front

What is the definition of conduction?

Back

Conduction is the transfer of heat from one object to another through direct contact.
