Do gas have quite high density?

Answer 1

Gas like every other thing in the universe, has density. Solid is very dense, liquid is dense but not as dense as a solid. Therefore, if everything in the universe has a density rate, a gas does have density, however, just a very low density.

Answer 2

Gases have a low density because the atoms or molecules of the gas have very high thermal energies. (This doesn't necessarily mean high temperature, but it does mean high thermal energy.) Gas atoms or molecules, with their high thermal energies, have high kinetic energies, too. The atoms and molecules are in violent motion and want no part of each other. They want to put as much distance between themselves and any other atoms or molecules as they can. This results in few atoms or molecules in a whole lot of space - and this transliates into low density. The thermal kinetic energy of gas atoms or molecules is so high that they will occupy as much volume as they can. The gas will have a low density as a consequence.

Answer 3

No.

According to the equation PV=nRT, the volume of a gas changes depending on the pressure and temperature of its environment. As the volume of the gas varies, the density also does, because d=m/v.

Answer 4

In general no. Gases, given the space of containment will spread out very rapidly

Answer 5

Yes, pressure is reversely proportional to volume (decrease)

Answer 6

No. Gases have very low density.

Answer 7

yes chlorine has 22.2

Answer 8

Gases have low densities.
