Understanding Properties of Matter

What was the main focus of Jane's experiment?

• To find the boiling point of water.

• To test the durability of the balloon.

• To observe the properties of matter.

• To measure the mass of the balloon.

Why did the balloon increase in size during the experiment?

• The balloon material expanded.

• The air inside the balloon expanded.

• The water temperature decreased.

• The balloon was overinflated.

What happens to the water level when the balloon expands?

• It decreases.

• It remains the same.

• It increases.

• It evaporates.

Which option correctly explains the increase in water level?

• The hot water increased in mass and occupied more space.

• The air in the balloon expanded and occupied more space in the water.

• The hot water expanded and occupied more space.

• The balloon expanded and increased in mass.

Why does the mass of the balloon remain unchanged?

• The water absorbed the air.

• The balloon material is very light.

• No air was added or removed from the balloon.

• The balloon was not fully inflated.
