Checking what you already know... about heating and cooling

When you sit at the dinner table, you probably wait until your food gets cool enough to eat, but you drink your water while it is still cold.

Click on ALL the correct statements you think are related to why our food get cooler, but our drinks get warmer at the dinner table.

• A. Heat energy from the food flows into the cooler air around it.
• B. Heat energy from the air flows into the cooler drink.
• C. Cold energy from the drink flows into the surrounding air.
• D. Cold energy from the surrounding air flows into the food.

If you marked A and B, you are on the right track. Heat energy only goes from something hot to something cold. As you go through this module, you may be surprised to find out that there really isn’t any such thing as cold energy.
