Question

This fruit floats because 25% of its volume is air?

Answer 1

Apples can float because 25% of their volume is air. If an item is more dense than water it will sink, it is less dense it will float. Apples are less dense than water, so they float

Answer 2

Answer:

Apple the fruit – often floats because of the high volume of air.

If an item, which is denser than water,  and that is the reason it will sink – otherwise, as apple will float surely.

The simple reason is that anything less dense than water (<1.0 g/mL) will float, and anything more dense than water (>1.0 g/mL) will sink.

Apple is less dense than water.
