Explanation:
Boiling Water - When water boils, the heat passes from the burner into the pot, heating the water at the bottom. This hot water rises and cooler water moves down to replace it, causing a circular motion.
Radiator - A radiator puts warm air out at the top and draws in cooler air at the bottom.
Steaming Cup of Hot Tea - The steam you see when drinking a cup of hot tea indicates that heat is being transferred into the air.
Ice Melting - Ice melts because heat moves to the ice from the air. As a result, the ice melts from a solid to liquid.
Frozen Food Thawing - Frozen food thaws more quickly under cold running water than if it is placed in water. This is because the action of the running water transfers heat into the food faster than if the frozen item was placed in still water.
