It rises the balloon It sinks It depends on the size of 4. Think about a pot of boiling water on your stove. As the water heats up: a) It becomes more dense and rises b) It becomes less dense and rises c) It becomes more dense and sinks d) It becomes less dense and sinks 5. When water on earth's surface heats up enough it evaporates (becomes water vapor) and rises. Water vapor cools as it rises through the atmosphere. Eventually, it gets cool enough that it condenses (becomes liquid water). What happens to the water after it cools and a) It rises b) It falls as rain c) It instantly evaporates d) It turns into carbon dioxide 6. Why do icebergs float? a) Icebergs are more dense than water b) Icebergs are less dense than water c Water has unique properties compared to many

Explanation / Answer

2) Since the density of ball is less than water it floats on the surface of the water

4) Due to boiling water becomes less dense and rises.

5) b) It falls as rain after getting heavy

6) Icebergs float since they are less dense than water.
