Which Fruit Has 25% Oxygen?
The question is slightly misleading. No fruit is composed of 25% oxygen by weight or mass. However, the kiwifruit (or kiwi) contains approximately 25% air by volume within its porous core. This air, of course, contains oxygen.
- Buoyancy: The kiwifruit's unique structure allows it to float due to this high air content (approximately 25% of its volume). This low density, coupled with its relatively small size, contributes to its buoyancy.
- Air Composition: The air within the kiwifruit is primarily composed of nitrogen and oxygen, with oxygen making up approximately 21%. Therefore, while the kiwifruit doesn't have 25% oxygen by weight, a significant portion of its volume is filled with air containing oxygen.
Other Fruits and Oxygen
Several fruits are rich in antioxidants and nutrients that support the body's oxygen utilization. Examples include avocados, mangoes, and pineapples. These fruits don't contain 25% oxygen but contribute to overall health and oxygen transport in the body. It is vital to understand that the question refers to the gaseous oxygen within the fruit's structure, not the oxygen chemically bonded within its components.
In summary: While no fruit contains 25% oxygen by weight or mass, the kiwifruit is notable for having approximately 25% of its volume filled with air, a mixture including oxygen.
