How will the flow of thermal energy between the three objects affect the temperature? Refer to the table showing the temperatures of several objects of the same mass and material.

• Thermal energy will transfer from the block to the ball until the block increases in temperature.

• Thermal energy will transfer from the block to the box until the box decreases in temperature.

• Thermal energy will transfer from the ball to the box until they come to the same temperature.

• Thermal energy will transfer from the box to the ball until they come to the same temperature.

Taylor and her friend Alex were heating up food in a microwave and it became too hot to eat, so the plate was placed on the counter to cool. Which of the following statements accurately identifies how thermal energy was transferred?

• Thermal energy was transferred from the air to the food because air has a lower density than the food.

• Thermal energy was transferred from the food to the air because food has a higher density than the air.

• Thermal energy was transferred from the food to the air because the temperature of the air was lower than the food.

• Thermal energy was transferred from the air to the food because the temperature of the food was greater than the air.
