Mercury vapor is odorless, colorless and very toxic. Even though liquid mercury evaporates slowly, a significant amount of mercury vapor can build up indoors after mercury is spilled, and it can be dangerous to breathe these mercury vapors.
Known as a liquid but obviously it can be all three. Mercury is a liquid at room temperature, it will solidify if you make cold enough, -40 C and be gas if you make it hot enoâ¦ugh, +357 C. It expands and contracts easily in this liquid form, which is why old thermometers used it.
