What is unique about radiation as a method of heat transfer?

• It requires a solid material

• It can travel through any material

• It only works in liquids

• It needs a gas to transfer heat

What does insulation do?

• Transfers heat

• Keeps heat from entering or exiting

• Increases heat flow

• Changes heat into electricity

What is the first step in a thermal electric plant?

• The generator creates electricity

• The turbine spins

• Natural gas is burned to release heat

• Water is changed into steam

What happens after the boiler changes water into steam?

• The generator creates electricity

• The steam causes the turbine to spin

• Natural gas is burned

• The turbine causes the generator to spin

What is the role of the turbine in a thermal electric plant?

• To burn natural gas

• To change water into steam

• To cause the generator to spin

• To create electricity

What is the final step in the process of a thermal electric plant?

• The boiler changes water into steam
