Some examples of elements that turn to gases at or lower than room temperature include nitrogen, hydrogen, oxygen and neon. Room temperature is usually defined as around 70 degrees Fahrenheit. Any element with a boiling point lower than this is a gas at room temperature.
There 12 elements that are gases at room temperature. Other examples include helium, krypton, argon and xenon. Radon, fluorine, chlorine and argon also become gases at temperatures far below the average room temperature.
Since these elements are gases at room temperature, this makes them useful for a number of applications. Neon, for example, is a gas commonly found illuminating advertising signs. Helium is a gas with a number of industrial applications, as well as being used to inflate balloons.
One of the most elements that is gaseous at room temperature is oxygen, as it is essential for humans to breathe. Oxygen has a boiling point of minus 295 degrees Fahrenheit.
Hydrogen is the most abundant element in the universe. It has a boiling point of minus 423.16 degrees Fahrenheit, so it requires temperatures near to absolute zero to become a liquid. Scientists hypothesize hydrogen makes up around 75 percent of the visible material in the universe.
