Rock is hundreds to thousands of times denser than any gas under normal conditions.
The 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.
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.
halogens are reactive gases and noble gases are non reactive!=)
The difference between permanent and variable gases is that variable gases change in response to activities in the environment, and permanent gases stay constant.
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.
Solids have a fixed shape and volume, with particles arranged in a regular pattern that allows for minimal movement. Liquids have a definite volume but take the shape of their container, with particles that can move past each other. Gases have neither a fixed shape nor volume, as particles move freely and fill the space of their container.
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, gases do not have the same density. The density of a gas depends on factors such as temperature, pressure, and the type of gas molecules present. So, different gases can have different densities.
All materials - including gases - have a density !
One is made from gases the other from liquids.
