Heat Transfer and Water Cycle Review

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. An example is feeling the heat from a campfire.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). An example is when heat moves in a circle in water.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. An example is touching a hot plate.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is also known as heat.

Front

What is a good heat conductor?

Back

A good heat conductor is a material that allows heat to move through it easily, such as metals.

Front

What is an example of heat transfer by radiation?

Back

Feeling the heat from a fireplace is an example of heat transfer by radiation.

Front

What is an example of heat transfer by convection?

Back

An example of convection is the way warm air rises and cool air sinks, creating a circular motion.

Front

What is an example of heat transfer by conduction?

Back

An example of conduction is when a metal spoon gets hot after being placed in a hot pot of soup.

Front

What happens to water when it evaporates?

Back

When water evaporates, it changes from a liquid to a gas, absorbing heat in the process.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.
