Which best explains why a hot air balloon floats?

The heated air expands to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.

The heated air expands to fill the balloon. The air in the balloon is now heavier than the surrounding air, causing the balloon to rise.

The heated air contracts to fill the balloon. The air in the balloon is now denser than the surrounding air, causing the balloon to rise.

The heated air contracts to fill the balloon. The air in the balloon is now lighter than the surrounding air, causing the balloon to rise.

On a warm sunny day, you will feel cooler wearing light colored clothes because they...

reflect more radiated heat energy.

are not as heavy as dark clothes.

If you put a metal spoon and a wooden spoon into a pot of boiling water, one will become too hot to touch. Why?

Metals conduct heat better than wood.

Wood conducts heat better than metals.

Metals pull in heat because heat is attracted to metals.

Wood isn’t as strong as metals.

You have a can of soda in your lunchbox that you want to keep cold. Which material will work best to keep it cold?

Your wool sweater wrapped around the soda because wool traps air.

Aluminum foil wrapped around the soda because metals transfer heat energy easily.

A paper towel wrapped around the soda because paper soaks up the moisture.

Wax paper wrapped around the soda because wax paper traps the moisture.

When you hold a metal coat hanger in a camp fire to roast a marshmallow, the coat hanger might become too hot to hold. Why might the coat hanger get too hot?

Metal atoms vibrate with more energy when they get hot, and they collide with atoms near them, which causes the neighboring atoms to vibrate.

The heat radiates along the coat hanger.

The heat builds up near the flame until it can’t hold it anymore and then moves along the coat hanger.

Since metals melt in fire, they react strongly to fire and get hot easily.

You take a cold can of soda off of a counter top. The counter top underneath the can feels colder than the rest of the counter. Which of the following explains this occurrence?

Some heat has been transferred from the counter to the soda.

The cold has been transferred from the soda to the counter.

There is no heat energy left in the counter beneath the can.

The heat beneath the can moves away into other parts of the counter top.

After cooking an egg in boiling water, you cool the egg by putting it into a bowl of cold water. Which of the following explains the egg’s cooling process?

Energy is transferred from the egg to the water.

Temperature is transferred from the egg to the water.

Cold moves from the water into the egg.

Energy is transferred from the water to the egg.

When the temperature of matter decreases the particles ...
