Tn Ready Review: Thermal Energy

What is the process called when heat is transferred through direct contact between materials?

• Radiation

• Conduction

• Convection

• Evaporation

Which of the following is an example of convection?

• Heat from the sun warming your face

• A metal spoon getting hot from a boiling pot

• Warm air rising and cool air sinking in a room

• A microwave heating food

Which method of heat transfer does not require the items to be in contact?

• Conduction

• Convection

• Radiation

• Insulation

Describe how a pot of water is heated on a stove using conduction, convection, and radiation.

• Conduction heats the pot, convection circulates the water, and radiation heats the air.

• Conduction heats the pot, convection heats the air, and radiation circulates the water.

• Conduction circulates the water, convection heats the pot, and radiation heats the air.

• Conduction heats the air, convection heats the pot, and radiation circulates the water.

Which of the following is an example of radiation?

• Boiling water in a pot

• Heat from a campfire warming your hands

• Ice melting in your hand

• A fan blowing air in a room

Predict what would happen to the temperature of a room if a heater is placed in one corner and explain why.

• The temperature would increase evenly throughout the room due to radiation.

• The temperature would increase near the heater due to conduction.

• The temperature would increase throughout the room due to convection.

• The temperature would decrease due to insulation.
