As a mineral expert with a background in geology and chemistry, I can provide some insights on the stability of minerals in the presence of air. Minerals are naturally occurring, inorganic, crystalline solids that have a defined chemical composition and a crystalline structure. They are not typically destroyed by air, but they can undergo various chemical reactions depending on the specific conditions.
Minerals and Air:
Minerals are generally stable under normal atmospheric conditions. They are not easily oxidized or reduced by the oxygen in the air, which is why they can remain unchanged for long periods of time. However, there are certain factors that can affect their stability:
1. Moisture: The presence of water can lead to the weathering of minerals. Some minerals are more susceptible to chemical weathering when in contact with water, which can lead to the formation of new minerals or the dissolution of the original mineral.
2. Temperature: While the statement suggests that minerals are unaffected by heat, it's important to note that extreme temperatures can cause physical changes in minerals. For example, high temperatures can cause thermal expansion or even lead to the melting of certain minerals.
3. Chemical Reactions: Minerals can react with other chemicals present in the air, such as acids from pollution, which can lead to dissolution or alteration of the mineral structure.
Vitamins and Air:
The stability of vitamins is a different matter. Unlike minerals, vitamins are organic compounds that are essential for various bodily functions. The statement provided is correct in pointing out that many vitamins are sensitive to heat, air, water, and fats. For example:
- Vitamin C (Ascorbic Acid): It is highly sensitive to heat and can be easily oxidized in the presence of air, leading to its degradation.
- Fat-Soluble Vitamins: Vitamins A, D, E, and K are stored in the body's fatty tissues and are more stable than water-soluble vitamins. However, they can still be affected by exposure to air and light, which can lead to oxidation.
- B Vitamins: As mentioned, vitamin K and niacin are quite stable, but other B vitamins like B1 (thiamine) and B2 (riboflavin) can be sensitive to light and air.
Conclusion:
In summary, while minerals are generally stable in the presence of air, they can be affected by certain environmental factors such as moisture and extreme temperatures. The stability of vitamins, on the other hand, is more variable, with many being sensitive to air and other environmental conditions. It is crucial to understand the specific properties of each mineral and vitamin to predict their behavior in different environments.

Virtually all minerals are unaffected by heat. ... With the exception of vitamin K and the B vitamin niacin, which are very stable in food, many vitamins are sensitive and are easily destroyed when exposed to heat, air, water, or fats (cooking oils).
