By tinting them.
Almost all of the principal gases in the atmosphere are colourless. Hence we see the air as colourless.
Yes, but only if you have an electron microscope
What gases cause air pollution
Air could be described as the space between objects. It consists of gases that we generally cannot see with the naked eye.
Yes. The gases ARE the air.
Air, which is a mixture of gases, exerts pressure. We can see this as we observe a breeze moving the leaves of trees around. Air can be compressed, and we can demonstrate that if we blow up a balloon. Air is transparent, and we can't see it. There are other properties of air that are a little hard to see as air is a very light, transparent gas mixture.
Solids: concrete, glass, steel Liquids: water, beer, wine Gases: air, carbon dioxide, methane
Noble gases are lighter than air. Hence balloons filled with noble gases will float in air.
Air itself is not a material; it is a mixture of gases. However, the main component of air, nitrogen and oxygen, are both transparent to visible light. This is why we can see through air with our eyes.
Without different gases there will be no air, if there is air, how can oxygen travel?
yes
Water or air dirty with gases or chemicals is polluted water or air.
