Air Properties and Functions
Introduction:
Air is a mixture of gases that surrounds the Earth. It is essential for the survival of living organisms and plays a crucial role in various natural processes. Let's examine the given statements to determine their accuracy.
(i) Air has no mass:
This statement is not true. Air does have mass. Even though air is composed of gases, each gas molecule has a certain mass. When these molecules combine to form air, their mass also gets combined. Therefore, air has mass and takes up space.
(ii) Air is needed for burning:
This statement is true. Air is required for burning processes. Combustion, which is the process of burning, requires three essential components known as the fire triangle: fuel, heat, and oxygen (present in air). In the absence of these components, burning cannot occur.
(iii) Air exerts pressure from all sides and on everything:
This statement is also true. Air exerts pressure in all directions, including upward, downward, and sideways. This pressure is known as atmospheric pressure. It is caused by the weight of the air above us, pressing down on the Earth's surface. Atmospheric pressure affects everything around us, including our bodies, objects, and even liquids.
Conclusion:
Based on the analysis, the correct answer is (ii) and (iii). Air does have mass, it is necessary for burning, and it exerts pressure from all sides. Understanding these properties and functions of air is vital in various scientific and everyday contexts.
