WitrynaGas is a type of matter that has no defined shape or volume. Gases can be made up of a single element, such as hydrogen gas (H 2), a compound, such as carbon dioxide (CO 2), or a mixture of several gases, such as air. The gaseous state is one of the four fundamental states of matter (along with the solid state, the liquid state and plasma). Witryna23 sie 2024 · Elements that exist as gases at room temperature and pressure are clustered on the right side of the periodic table; they occur as either monatomic gases (the noble gases) or diatomic molecules (some halogens, N 2, O 2).
