Name 3 substances that are solids at room temperature.  Do the same for liquids and gases.

Answer and Explanation:

Solids:

We can name some chemical elements that in nature are solids at room temperature:

Aluminium (Al): it is a dultile metal with a color between silver and white.

Sulfur (S₈): it is a pale yellow solid.

Zinc (Zn): it is a metallic brittle solid.

Liquids:

Some substances that are liquids at room temperature are:

Water (H₂O): it is a subtance composed by 2 atoms of hydrogen and 1 atom of oxygen. It is a clear, limpid, odorless liquid.

Bromine (Br₂): it is a homogenoeus halogen which is liquid at room temperature. It has a color beteween red and brown.

Mercury (Hg): this heavy metal is liquid at room temperature.

Gases:

Hydrogen (H₂): it is a colorless, odorless and hightly inflammable gas.

Oxygen (O₂): a diatomic gas, without odor neither color, with an important role in biological proceesses.

Nitrogen (N₂): other diatomic gas, which is inert (it does not react easily).
