The density of water at 4 degrees Celsius is 1.000 g/mg is it chemical or physical property?
Kaylis [27]

Answer:

Physical Property

Explanation:

Density, mass, volume, color, melting and boiling points, etc. are all physical properties. No matter what changes, the chemical makeup stays the same.

Flamability, acidity, toxicity, etc. are chemical properties, because they chemically change the makeup of the object/thing.
