1 molar Hydrochloric acid has a theoretical (actual is pretty close too) of 0. The pH is defined as the negative logarithim to base 10 of the Hydrogen ion concentration.
So - log10[1] = 0
Battery acid being stronger than that has a pH of zero (actually slightly negative).
Examples: methane, nitrogen, oxygen, etc.
When a substance changes from a liquid to a gas energy is absorbed. When a substance changes from a gas to a liquid energy is released.
Helium is pure as it is on the periodic table.
It depends on what substance the gas is.
Answer: computer says no?Answer: Also zero. This is hypothetical; an extrapolation. No real substance can be cooled all the way to zero Kelvin, and no gas would remain a gas at temperatures approaching that temperature.
:0
air is a substance because air is a gas and a gas is a substance.
Yes, gas is a pure substance.

The substance of Saturn is gas
Chlorine is a substance. It is not a mixture. At room temperature, chlorine is a gas. The color of the gas is yellowish green.
Any substance, when its gas is cooled below its condensation temperature.
Ammonia gas is a single substance because it is a single compound, NH3.
It depends on what substance the gas is.
