What are the 10 properties of air?
Answers
Answer:
Explanation:
As mentioned earlier, gases are matter. There are certain properties of gases like any other matter. Some common properties are as follows:
Colourless and Odourless:
Air generally has no colour or odour. It is an invisible matter that can only be felt. All living things breathe air for their survival. Moving air is called wind.
Occupy Space:
It is a mixture of different gases. Hence, like every other matter, they also occupy space. On blowing, a balloon expands because the air being blown into it fills up the empty space.
Air Exerts Pressure:
It has weight, and the pressure exerted by the weight of air is known as air pressure. Due to gravity, this mixture of gases near the surface is denser than at high altitudes. This is why the gaseous atmosphere in the mountains is thinner than that at the surface.
Expansion:
Another property is its expanding property. On heating, it expands and occupies more space. The more it expands, the thinner it becomes. Hence, the pressure of the warm wind is lower than that of cold wind.
