• conduction

• convection

• radiation

• all of these

Which of the following is an example of conduction?

• A dog's bowl of water warms up out in the sun.

• Leftovers become warm when reheated in the microwave.

• Campers warm up while sitting by a campfire.

• A metal spoon becomes warm when placed in a cup of hot tea.

Which of the following is an example of convection?

• the rays of the Sun warming the earth

• a hot object transferring heat to a cooler one

• hot air rising and cooler air falling

• a hot oven warming the air around it
