Why is it important to use room-temperature water in the container?

• To make the water look clear

• To accurately observe the behavior of hot and cold water

• To prevent the container from breaking

• To ensure the food coloring mixes well

What is the purpose of adding food coloring to the hot water?

• To cool it down

• To make it boil faster

• To differentiate it from the cold water

• To make it look pretty

What happens to the blue ice cube when it is dropped into the water?

• It dissolves immediately

• It sinks to the bottom

• It changes color

• It floats on top

Why does the red hot water float on top of the blue cold water?

• Because it is colder

• Because it is heavier

• Because it is more colorful

• Because it is less dense

What can be observed between the layers of red and blue water?

• A layer of green water

• A layer of bubbles

• A layer of mixed colors

• A layer of clear water

What does the experiment demonstrate about the behavior of air?

• Warm air stays at the bottom

• Warm air sinks and cold air rises

• Warm air rises and cold air sinks

• Warm air and cold air mix evenly
