Yes!

No. First of all, liquids are not gasses. Liquids and gasses are two different states of matter. Second, you can have any mass of liquid or any mass of gas. Third, liquids are denser than gasses, meaning they have more mass for a given unit of volume.
Different gasses have different masses.
Anything with mass; solids, liquids, gasses.
They get highly polluted with gasses.
if some of it gasses off wend mixed
The Sun is a burning mass of gasses, so it has no hardness, just flame.
Heating gasses or liquids has no effect on their masses.
Air consists mostly of Nitrogen. Nitrogen's Molar Mass is 14.01. Carbon Dioxide's Molar Mass is 44.01. Therefore CO2 is more dense that Air (surrounding gasses)
Heating gasses or liquids has no effect on their masses.
Yes, gases have mass because they consist of individual particles (atoms or molecules) that have their own mass. The mass of a gas is determined by the combined mass of its individual particles.
None. Just a huge amount of different gasses. Saturn has no land mass and no minerals on it.
