[PDF] matter substances

All matter can be classified as either a substance (element or compound) or a mixture (heterogeneous or homogeneous) Substance can write chemical

Air is a mixture and not a compound because air can be separated into its constituents such as oxygen, nitrogen etc. by fractional distillation of liquid air. Air shows the properties of all the gases present in it.

  • Is pure air a substance or mixture?

    Although air is a mixture consisting of roughly 78% of nitrogen, 21% of oxygen, and trace amounts of other gases and moisture, air is homogeneous and has distinct properties without phase changes in its composition in many thermodynamic processes. In such conditions, we can treat air as a pure substance.

  • Is air a substance of a mixture?

    Air is nothing but a mixture of a variety of gasses. The air in the atmosphere consists of nitrogen, oxygen, which is the life-sustaining substance for animals and humans, carbon dioxide, water vapour and small amounts of other elements (argon, neon, etc.).

  • Is air always a pure substance?

    - Air is not supposed to be considered as a pure substance. Because air is a mixture of different gases. - Air mostly contains nitrogen and oxygen in about 78% and 20% respectively. Note: Elements and compounds have a constant composition throughout and can thus be said as pure substances.
  • Air contains oxygen and nitrogen as its major constituents of air. These gases retain their properties in the air. Hence, air is considered a mixture.
