All gases have same kinetic energy of molecules at same conditions.
gases
- organic or inorganic gases- common or noble gases- toxic or nontoxic gases- natural or artificial gasesetc.
Hydrogen and helium are the two main gases in the Universe.
Solids and gases have a number of things in common. The main similarity between the two is that they can be converted into liquid state.
Nitrogen and Oxygen are the most common gases in the atmosphere.
Both are gases.
they can flow
Nitrogen, carbon dioxide and oxygen are common gases althrough carbon dioxide's quantity is not much. There isn't 4th 'common' gas present in the air.
The two gases that are most common in interstellar clouds,consist mostly of gas,especially hydrogen and helium.
The two most common gases in Earth's atmosphere are nitrogen (approximately 78%) and oxygen (approximately 21%).
These gases are nitrogen, oxygen, argon, carbon dioxide.
The noble gases
