Properties of gases
Oxygen Gas
Oxygen: Oxygen is a colorless, tasteless and odorless gaseous element that constitutes 21 percent of the atmosphere. A chemical element with symbol O, the atomic number of oxygen is 8. Oxygen exists in all three forms - liquid, solid, and gas. However, the liquid and solid forms have color, which is blue, but gas neither has color nor has odor and taste.
To change from a gas to a liquid, oxygen requires a temperature of 182.96°C, and on the other hand, at a temperature of -218.4°C, it can be solidified or frozen.
| Physical Properties of Oxygen | |
| Color | Colorless |

Nitrogen Gas
Nitrogen: Nitrogen, symbol N, is the chemical element of atomic number 7. It is a common normally colorless, odorless, tasteless and mostly diatomic non-metal gas. The element is primarily found as the gas molecule; it comprises of about 78% of Earth's atmosphere. Scottish physician Daniel Rutherford discovered that nitrogen is separable component of air in 1772.
To change from a gas to a liquid, oxygen requires a temperature of 182.96°C, and on the other hand, at a temperature of -218.4°C, it can be solidified or frozen.
