Heat Transfer 5th Grade Science

Which best explains how convected heat causes a hot air balloon to stay in the air?

• The heat is falling and replacing cooler air.

• The heat is produced from the rising of air currents.

• The heat is absorbed through the balloon from the sun.

• The heat is rising and circulating, causing the balloon to stay up in the air.

Which best explains how candle wax is shaped into a mold?

• Heat is added to candle wax to melt it so it is more flexible and can take the shape of the mold.

• Heat is added to candle wax to melt it so it is less flexible and can take the shape of the mold.

• Cold is taken away from the candle wax so it is more flexible and can take the shape of mold.

• Cold is taken away from candle wax so it is less flexible and can take the shape of mold.

On very hot days, animals will often find a patch of dirt on the ground to lay in to keep cool. Which best explains how laying on the ground and dirt keeps the animal cool?

• The coolness from the ground is transferred to the animal's body, lowering the animal's body temperature.

• Dirt on the ground protects the animal from the heat in the air, lowering the animal's body temperature.

• The animal's body temperature does not change, but the dirt makes the animal feel cooler.

• Heat from the animal's body is transferred to the ground, lowering the animal's body temperature.
