No, pure air is not homogeneous because it contains a mixture of different gases such as nitrogen, oxygen, carbon dioxide, and others. Each gas has a specific composition and properties, making the air a heterogeneous mixture on a molecular level.
Pure air itself is invisible and does not have a color. However, when light passes through clean air, it can appear translucent due to scattering of light particles. This can be seen as a hazy or blurry effect, especially when looking at distant objects.
One can make oxygen from air through a process called fractional distillation. This involves cooling and compressing air to separate its components, with oxygen being collected as a pure gas.
A pure vacuum is a space devoid of matter, including air and particles. It has no pressure, temperature, or density. Light travels through it at its maximum speed. It is an idealized concept as achieving a perfect vacuum is impossible in practice.
Audiometry is used to compare bone and air conduction. It measures the threshold at which a person can hear pure tones through bone and air conduction. The results help diagnose hearing loss and determine the type of hearing loss present.
vapor pressure of a pure solvent is the pressure needed for the gas to escape the pure solvent in vapor form. its partial pressure in this case will be the pressure of that escaped vapour (in the mixture of air). in simpler terms vapor pressure describes a single condensable system (just the vapor of the solvent and the liquid state of the solvent) while its partial pressure describes the multicomponent system (air). they are essentially the same thing describing different systems
Yes, iron is a chemical element.
reason for air is not pure
air is not pure
Table salt (NaCl) is a compound not a mixture.
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.
Yes: for example destillation, crystallisation, freezing .....
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
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.
