∙ 7y agoThe difference between permanent and variable gases is that variable gases change in response to activities in the environment, and permanent gases stay constant.
In the homosphere the concentration of gases remains the same throughout, and the gases are mixed, always in the same proportions. In the heterosphere the concentration of gases is different in different places, and the gases are typically in the form of layers, rather than mixed together.
The heat trapping ability of some gases in the atmosphere can be compared to a glass greenhouse's ability to trap heat. Thus, the term "greenhouse effect" was created.
halogens are reactive gases and noble gases are non reactive!=)
ice floats on top of water due to its lower density.... similarly, the gases with lower density lies in the upper atmospheric layers and the ones with larger density lie on the lower most atmospheric layers. so the overall density of air decreases with height.

there is no far difference b/w coal & charcoal.Charcoal has greater surface area as compared to coal and can absorb gases and other impurities better.
What is the difference between solid and gas in terms of their fluidity
they all come from water
Gas, as well as everything in the universe has density, though some densities are either too high or too low to be detected but for gases, the density can vary over a wide range because the molecules are free to move.Gases have a lower density compared to liquids because their particles are more spaced out hence occupies more volume. Gases have no fixed shape or volume and will always spread out to fill any container.
There will be a discharge if:* There is a voltage difference (this can be compared to a pressure difference, in gases), and * There is a way for the surplus charge to move from one side to the other.
No, it isn't.
As gases are heated up, its volume increases, resulting in a decrease of density.
The density is a physical characteristic, specific for each material, including gases.
No, there are actually fairly large variations between different gases. Also, for a single gas the density depends greatly on the temperature and pressure.
All materials - including gases - have a density !
One is made from gases the other from liquids.
