Heat Energy by Pictures

When Julie was cooking macaroni she noticed that it would rise to the top of the boiling water and then sink back to the bottom of the pot. This is most likely because

• The convection of heat within the water was creating a current.

• The convection of air around the pot was creating a current.

• The conduction of heat within the water was creating a current.

• The conduction of air around the pot was creating a current.

Which substance will conduct the least amount of heat?

• glass
• copper
• plastic
• aluminum

Which best describes the process of conduction?

• When two objects touch, the heat is transferred into the air.
• When two objects touch, the heat from the hotter object is transferred to the cooler object.
• When two objects touch, the cool air from the cooler object is transferred to the hotter object.

Which is an example of heat transfer by convection?

• a glowing light bulb
• heating the atmosphere
• cooking using a microwave oven
• heating a piece of metal in a flame

Kelly was sunburned at the beach, and her mother applied lotion to the burn. Why did this make her sunburn feel better?

• The coolness from the lotion was conducted into the burn.
• The coolness from the lotion was radiated into the burn.
• The heat from the burn was conducted into the lotion.
• The heat from the burn was radiated into the lotion.

Mrs. Stallings' class is learning about heat transfer. Her class observes a pot of boiling water and describes the process. The students note that as the water at the bottom heats up, it rises. The cool water at the top falls, and the cycle continues. Which best describes the process the students are observing?

• conduction
• convection
• radiation
• transformation
