Tempature and humidity are almost always the 2 traits given, even if the terms are vague, such a as a warm moist air mass or a cold dry air mass. The terms are in reference to the air mass in an area before the new one being described.
Oxygen
Density of substance = mass of substance / volume mass of substance = density x volume
As the air bubble increases in volume, its mass remains constant. Because the mass remains constant but volume increases, density will decrease.
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
Volume = mass / Density Mass = Volume * Density Density = Mass / Volume
No. An air mass is a section of the atmosphere with certain characteristics of temperature and humidity that distinguish it from nearby air masses. Air pressure is, in simple terms, how much the air is pressing down on the surface.

no you would not describe a warm air mass cause you don't know where the warm air mass is and whether or not it is warm and if you can describe it.
the air density is 40,000
mass,density,and pressure. :)
its density / mass
Density = Mass / Volume. So, if your volume stays the same, and there is a greater mass of air, then the density goes up.
Oxygen
That question doesn't mean anything, mass is mass. If you are asking which has a greater mass per unit volume, also known as density, then the air will have a lower density than clay.
