Which best explains how a hot air balloon uses convection to stay in the air?

• Rising air currents produce heat

• The heat rises and circulates, allowing the balloon to float in the air

While cooking pasta you observe that the pasta starts at the bottom of the pot, rises to the top, and then sinks back down to the bottom of the pot. This happens because

• Convection of the water creates a current

• Conduction of the water creates a current

• A current of air around the pot is created by convection

• A current of air around the the pot is created by conduction

You put a pot of water on the stove and boil it, why does all the water have the same temperature?

• Steam and heated molecules rise: convection

• The metal reflects heat to the center

• The burner radiates heat through the water

• The stove heats the bottom and evaporation heats the top
