reason for air is not pure
air is not pure
A pure air can be prepared only in laboratory, by mixing the components. Note that air is not a compound but a mixture of gases. In the nature pure air don't exist - the air is polluted.
The science term for cold air is "temperature inversion." This phenomenon occurs when a layer of cold air is trapped near the ground by a layer of warmer air above it. Temperature inversions can lead to fog, smog, and poor air quality.
No
No. Air is not pure substance. Air has all dust and dangerous gases with it. From place to place its composition changes.
Pure air is homogeneous because all components are completely miscible.
No, there is 21% oxygen in air.
As per my knowledge pure substance does not have anything else added to it. Air and water are pure substances that exist in nature. A pure substance cannot be taken apart to locate more substances.
Air is a mixture.
pure air is homogeneous but dusty air is heterogeneous
The ultrapure water is not conductive.
