Chlorine gas. Chlorine is an irritating green-yellow diatomic gas that is extremely reactive, and has a gaseous density of 3.2 × 10 −3 g/cm 3 (about 2.5 times heavier than air). It condenses at −34.04 °C to an amber-coloured liquid and freezes at −101.5 °C into a yellow crystalline solid.
In the stratosphere, CFC-113 can be broken up by ultraviolet radiation (UV, sunlight in the 190-225 nm range), generating chlorine radicals (Cl•), which initiate degradation of ozone requiring only a few minutes: [10] [11] CClF 2 CCl 2 F → C 2 F 3 Cl 2 + Cl• Cl• + O 3 → ClO• + O 2. This reaction is followed by: ClO• + O → Cl ...
Boiling liquid oxygen This is a list of gases at standard conditions , which means substances that boil or sublime at or below 25 °C (77 °F) and 1 atm pressure and are reasonably stable. List
To determine the density of a liquid or a gas, ... of its maximum density Water (salt) 1,030: 3% Liquid oxygen: ... air at 1 atm pressure T (°C) ρ (kg/m 3) −25: 1 ...
ρ is the gas mass density, ... D is the diffusion coefficient in gas or liquid filling the pores, ... 25: 0.260 Oxygen (g) Air (g) 25: 0.176
Since the density of dry air at 101.325 kPa at 20 °C is [9] 0.001205 g/cm 3 and that of water is 0.998203 g/cm 3 we see that the difference between true and apparent relative densities for a substance with relative density (20 °C/20 °C) of about 1.100 would be 0.000120. Where the relative density of the sample is close to that of water (for ...
In gas dynamics we are interested in the local relations between pressure, density and temperature, rather than considering a fixed quantity of gas. By considering the density ρ = M / V {\displaystyle \rho =M/V} as the inverse of the volume for a unit mass, we can take ρ = 1 / V {\displaystyle \rho =1/V} in these relations.
