Unit Review Energy Transfer and Heat

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. For example, when you touch a hot stove, heat transfers from the stove to your hand.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves. An example is the heat you feel from the sun or a lamp.

What is an example of conduction?

Back

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

Front

What is an example of convection?

Back

Boiling water in a pot is an example of convection, as the hot water rises and cooler water sinks.

What is an example of radiation?

Back

A lizard warming itself under a lamp is an example of radiation.

Front

What type of energy does a lamp produce?

Back

A lamp produces light energy.

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 happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, creating convection currents.

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.
