Answer:
Boiling water - The heat passes from the burner into the pot, heating the water at the bottom. Then, this hot water rises and cooler water moves down to replace it, causing a circular motion.
Radiator - Puts warm air out at the top and draws in cooler air at the bottom.
Steaming cup of hot tea - The steam is showing heat being transfered into the air.
Ice melting - Heat moves to the ice from the air. This causes the melting from a solid to liquid.
Hot air balloon - A heater inside the balloon heats the air and so the air moves upward. This causes the balloon to rise because the hot air gets trapped inside. When the pilot want to descend, he releases some of the hot air and cool air takes it place, causing the balloon to lower.
Frozen material thawing - Frozen food thaws more quickly under cold running water that if it is placed in water. The action of the running water transfers heat into the food faster.
