What was the first balloon filled with in the experiment?

• Air and a little water on the outside

• 40 mils of water

• 20 mils of water

• Just air

Predict the order in which the balloons will pop based on their contents.

• 40 mils, 20 mils, water-wiped, air

• Air, water-wiped, 20 mils, 40 mils

• 20 mils, 40 mils, air, water-wiped

• Water-wiped, air, 40 mils, 20 mils

How long did the balloon with just air take to pop?

• 7 minutes 57 seconds

• 1 minute 44 seconds

• 24 seconds

• 22 seconds

Which balloon took the longest to pop and how long did it take?

• Just air, 22 seconds

• 20 mils of water, 1 minute 44 seconds

• 40 mils of water, 7 minutes 57 seconds

• Balloon with water-wiped bottom, 24 seconds

Why does the balloon with 40 mils of water take longer to pop compared to the one with just air?

• Because the air inside insulates better than water.

• Because water has a high specific heat and absorbs more energy.

• Because the balloon material is thicker.

• Because the heat source was weaker for this balloon.

How does water's specific heat affect the climate?

• It causes rapid temperature changes in the environment.

• It has no significant effect on the climate.

• It buffers the climate by absorbing heat slowly.

• It increases global warming.

What is an example of how water's specific heat protects organisms?

• It prevents fish from becoming frozen or boiled easily.

• It helps in the migration of aquatic animals.

• It increases the metabolic rate of aquatic organisms.

• It allows fish to swim faster.
