Energy transfer

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another.

Front

What are the three main types of energy transfer?

Back

The three main types of energy transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

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

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

Define radiation.

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What determines the temperature of an object?

Back

The temperature of an object is determined by the speed of the atoms within it.

Front

How does energy move when ice is placed in warm water?

Back

Energy moves from the warmer water to the colder ice through conduction.

Front

What happens to warm air over water?

Back

Warm air rises and is replaced by cooler air, demonstrating convection.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in everyday life?

Back

An example of convection is boiling water, where hot water rises and cooler water sinks.
