Which of the following is NOT true regarding the properties of air?a)A...
Air has no mass.
The statement that air has no mass is not true. Air is composed of molecules, primarily nitrogen, oxygen, and trace amounts of other gases. These molecules have mass, although it is very small on an individual scale. However, when you consider the vast number of molecules present in a given volume of air, the total mass becomes significant.
Explanation:
1. Air occupies space:
Air is a matter and occupies space. It is made up of tiny particles called molecules, which are constantly in motion. The movement of these molecules allows air to fill up the space in a container or a room.
2. Air exerts pressure:
Air molecules are constantly colliding with each other and the surfaces around them. This collision creates a force, which is known as air pressure. Air pressure is the force exerted by the weight of the air above a particular area. This is why we can feel the pressure of air when it pushes against our skin or blows against objects.
3. Air has mass:
Air is made up of molecules, and molecules have mass. While the mass of individual air molecules is very small, the total mass of a given volume of air can be significant. This is why we can feel the weight of the air pressing down on us, especially at higher altitudes.
4. Air cannot be seen:
Air is transparent and cannot be seen with the naked eye. However, we can observe the effects of air, such as the movement of objects in the wind or the presence of clouds. We can also feel the presence of air through its pressure and the sensation of wind on our skin.
Therefore, the correct answer is option 'C' - Air has no mass, as air does have mass due to the presence of molecules.
