pressure is equivalent to that of 13.6cm Mercury column
It means that is has the same pressure as that of a column of mercury (symbol Hg), of that height. As far as I know, mmHg is usually used, rather than cm.
At constant pressure the temperature and the volume of a gas are directly related; this the Charle Law.
The speed of sound in a gas does not depend on pressure.See related links.There are limits to the validity of this statement because it is valid for gasses that behave as "ideal" gasses. Thus, when near a pressure and temperature that is close to the point that the gas will condense into a liquid, this statement fails. For air, at all the temperatures which we experience, the speed of sound in air is independent of pressure.

Gas Pressure
Are you stating or asking ? If that's a statement, then it's an incorrect one. At constant temperature, the product of (pressure) x (volume) is constant. So, if the volume changed by a factor of 3, the pressure must also change by a factor of 3 ... the pressure must triple.
At constant pressure the temperature and the volume of a gas are directly related; this the Charle Law.
If the gas is neutral this would mean the atom would also contain 136 protons, thus its atom number would be 136. Such an element has never been made (it does not occur naturally) and it would probably be unstable.

Regnault's Law is a statement in physics that says that the specific heat of a gas at constant pressure is the same whatever the pressure.

gas under pressure means where there is alot of high leaked gas which may be a health hazard
It means that if the gas is allowed to expand into a larger volume, the pressure - inside the container that contains the gas - will be less.
