Thermal Energy Review (Unit 5)

Which type of thermal energy transfer is illustrated in the diagram shown above?

• Electromagnetic waves of radiation

• Direct transfer of thermal energy by conduction

• Heat rising, cooling, and sinking by convection

• All three types of thermal transfer are illustrated

A student is drinking a cup of hot chocolate as they sit by a campfire on a chilly evening. They know that the cup of hot chocolate transfers thermal energy to the surrounding air. The heated air over their cup of hot chocolate expands and rises and is replaced by cooler, denser air.

This method of energy transfer is —

• convection

• condensation

• conduction

• radiation

A student is standing with their back facing a campfire. The student notices that their back is much warmer than their chest. They know that thermal energy is being transferred from the fire and that this method of energy transfer can happen even if no air is present.

This method of energy transfer is —

• convection

• condensation

• conduction

• radiation

Which picture best illustrates thermal energy transfer by conduction?

• 
• 
• 
• 

How does transfer of thermal energy by radiation differ from convection and conduction?

• Convection and conduction transfer thermal energy through solids, liquids, or gases.

• Radiation can transfer thermal energy through space in addition to solids, liquids, or gases.

• Radiation requires direct contact between particles for thermal energy transfer.

• Convection and conduction use currents to transfer thermal energy in solids, liquids, or gases.

The diagram below shows an ice cube placed in a hot pan.

Thermal energy is being transferred to the ice cube from the pan shown above by —

• convection

• conduction

• radiation

• conservation

A beaker with water is placed on a hot plate to increase the temperature of the water.

What forms of energy transfer occur while the hot plate is turned on?

• Radiation occurs where the hot plate touches the beaker. Convection occurs in the movement of the water.

• Conduction occurs where the hot plate touches the beaker. Radiation occurs in the movement of the water.

• Convection occurs where the hot plate touches the beaker. Conduction occurs in the movement of the water.

• Conduction occurs where the hot plate touches the beaker. Convection occurs in the movement of the water.

What type of heat transfer occurs when you touch a metal seat with your hand and the seat feels cold?

• Radiation

• Convection

• Conduction

• Transpiration

What is an example of thermal energy transfer by radiation?

• A metal spoon becoming hot in a bowl of soup

• Water boiling in a pot on a burner on the stove

• The Sun heating the surface of the Earth

• A hot air balloon releasing gas and rising

A cook is boiling corn on a stove as shown in the picture.

How does the process of boiling corn demonstrate conduction?

• Thermal energy is transferred from the hot burner to the pan by contact.

• Thermal energy is transferred through the water when is rises and sinks.

• Thermal energy is transferred from the burner to the water by contact

• Thermal energy is transferred throughout the water as it bubbles to a boil.
