Mercury/Boiling point
What happens to mercury in a vacuum?
A vacuum cleaner or broom will break the mercury into smaller drops and spread it around more. Tiny mercury droplets will settle throughout the area, increasing the spread of the mercury in the room. The droplets will evaporate faster and increase your chance of breathing high levels of mercury vapor.
Does mercury vaporize in vacuum?
No; mercury will evaporate into the vacuum, reaching an equilibrium state where the partial pressure of the mercury vapour (equal to the total pressure if it was a good vacuum to start with) is equal to the vapour pressure of mercury at whatever temperature the apparatus is at – at 25˚C that would be about 0.226Pa.
What temperature does mercury evaporate?
356.73 °C
The only other element that is liquid under these conditions is bromine, though metals such as caesium, gallium, and rubidium melt just above room temperature. With a freezing point of −38.83 °C and boiling point of 356.73 °C, mercury has one of the narrowest liquid state ranges of any metal.
At what temperature does mercury expand?
It has a short scale between 35—430C. This is because the optimal body temperature is 370C. It has a constriction to prevent back flow of the mercury into the bulb….THERMAL EXPANSION.

At what temperature does mercury freeze?

How do you get mercury out of carpet?
Sprinkle sulfur powder over the contaminated area and rub it gently all over the surface and into the cracks with a paper towel. Sulfur powder binds with mercury. Use a paper towel dampened with water followed by wiping with another damp paper towel to clean up the sulfur and mercury.
What temperature does mercury freeze?
How do you neutralize mercury?
What is the boiling point of mercury at room temperature?
Mercury – Boiling Point Boiling point of Mercury is 357°C.
What happens to Mercury when heated or cooled?
When heated or cooled, mercury expands or contracts at a rate that is more constant than most other substances. Also, it has a wide range of temperatures between its boiling and freezing points. In 1714, German-Dutch physicist Gabriel Daniel Fahrenheit developed the mercury thermometer.
What is the freezing point of a mercury thermometer?
Freezing Point. In addition to its expanding and contracting with temperature, liquid mercury freezes solid at -38.83 °C (-37.89 °F). Because of this, mercury thermometers have limited utility in very cold places where temperatures dip to below mercury’s freezing point.
Why was Mercury used to measure the temperature of water?
With mercury as the measuring fluid, temperatures could be recorded well above water’s boiling point and below its freezing point. Using mercury also allowed the degrees to be marked more accurately in finer subdivisions.
