Properties of Air:
Air is a mixture of gases that makes up the Earth's atmosphere. It has several properties that are important to understand in various scientific contexts.
Air exerts pressure:
One of the properties of air is that it exerts pressure. This pressure is known as atmospheric pressure and is caused by the weight of the air pushing down on the Earth's surface. This pressure is essential for many natural processes and phenomena.
Air has weight:
Another property of air is that it has weight. Even though air may seem invisible, it is made up of molecules that have mass and therefore contribute to the overall weight of the atmosphere. This weight is important in understanding concepts such as buoyancy and density.
Air occupies space:
Air is a form of matter, and like all matter, it occupies space. This means that air takes up physical space and can be compressed or expanded depending on various factors such as temperature and pressure. Understanding how air occupies space is crucial in fields like meteorology and physics.
Not a property of air:
The statement "Air is a biotic component of the environment" is not accurate. Air is not a living organism and therefore cannot be considered a biotic component of the environment. Instead, air is composed of non-living gases like oxygen, nitrogen, and carbon dioxide. Biotic components refer to living organisms such as plants, animals, and microorganisms that interact with each other and their environment.

Explanation:
To determine which property of air is not correct, let's examine each option:
A: Air exerts pressure: This is true. Air molecules exert pressure on the objects they come into contact with.
B: Air has weight: This is also true. Air is made up of molecules, which have mass and therefore, weight.
C: Air is biotic component of environment: This statement is not correct. Air is not a biotic component of the environment. Biotic components refer to living organisms such as plants, animals, and microorganisms. Air is composed of non-living gases like nitrogen, oxygen, carbon dioxide, and others.
D: Air occupies space: This is true. Air molecules occupy space and can fill containers.
Therefore, the correct answer is C: Air is biotic component of environment because it is the only option that is not a property of air.
