Why does a pumpkin float in water?

-because the water is more dense

-because water is lighter

-because it is heavier than water

-because it is more dense than water

Answer: Because the water is more dense.

Explanation: Any object that is less dense than water will float. Since the pumpkin is less dense than water, the water is able to push the pumpkin up, so that it floats. On the other hand, objects denser than water will sink. Pumpkins aren't very dense even though they're large, it's mainly hollow inside causes the pumpkin weigh less.

The correct answer is that water is more dense than a pumpkin. Objects that are less dense than water will float in it. Another example of separation by density is how oil and water won't mix.
