Why a watermelon floats?

Answer 1

Well, not all fruits float. All fruits are designed differently, which determines if they float or sink. The fruits that float have air. If more air takes up the object, it holds the object up helping it float. For example, an apple. The apple will float but not as much as an Styrofoam block. The apple can float because the apple's core has seeds AND air.

Answer 2

I'm not sure they do. Without experimental observational evidence,

or any reports in the journals, I'll have to take your word for it.

If a strawberry (or anything else) floats in water, it can be explained

with reference to the fact that the density of a strawberry is less than

the density of water.

Answer 3

An apple floats because 80% of an apple's volume is air.

Answer 4

it is to do with the density of the fruit the melon has a lower density than the grape and covers a larger surface area in the water

Answer 5

Any object will float on water (or another liquid) if the object has less density than the water (or other liquid).

Answer 6

If it does, indeed, float, you can safely assume that the reason is because it is less dense than water.

Answer 7

The specific gravity is less than water

Answer 8

its because of buoyancy.

Answer 9

Because of the shape of the watermelon
