Thermal Energy Transfers

Which of the following will happen?

• Energy in the form of heat will flow from the rock to the ground, and the temperature of the rock will increase

• Energy in the form of heat will flow from the ground to the rock, and the temperature of the rock will increase

• Energy in the form of heat will flow from the rock to the ground, and the temperature of the rock will decrease.

• Energy in the form of heat will flow from the ground to the rock, and the temperature of the rock will decrease.

Laura bruised her knee.  She applied an ice pack to the bruised area.  When she removed the ice pack from the injured knee, she noticed that the temperature of her skin was lower than the rest of her body.  What is the most likely reason this occurred?

• Increased blood flow due tothe ice pack caused the skin to be cooler

• The cooling energy of the ice pack was transferred to the skin.

• Heat energy from the skin was transferred to the ice pack.

• The air surrounding the ice pack cooled the skin.
