can you evaporate gold?

Question

While the metal is in liquid state can you further burne it with a much more higher temperature can you evaporate it? if you can , can you specify the grade ( in celsius)

Answer 1

Yes, every element has a melting point and a boiling point. The boiling point of gold is 2807.0 °C

Answer 2

Evaporation is not quite the same as boiling. Evaporation takes place at the interface of a liquid and the atmosphere. Molecules that have a higher energy than the avg kinetic energy of the liquid will escape into the atmosphere or evaporate. Boiling takes place at a higher temp where all of the liquid molecules have enough energy to become gas or vapor and overcome the atmospheric pressure on top.

So you can boil the liquid gold in two ways: raise its temp to the boiling point or lower the pressure above the liquid. It's not practical to get that hot, so often gold is turned into vapor in a vacuum chamber where it eventually boils at a lower temp. It's called vacuum sputtering.

It's usually pure gold, like 99.99%, though you could get various grades if you adjust a few things.

Answer 3

Gold boils at 2856C. So, it can be evaporated at that temperature.

Answer 4

Under low pressure - yes you can.

The metal is electrolytically sublimed, goes from the solid state directly to gas with an electric current. I have no idea of the current.

They claim it to be 99.9% gold

Answer 5

Any and all elemnts have a boiling point where it begins to evaporate.

Answer 6

Any element can be turned into a gas if enough heat is applied, yes.

Answer 7

All elements can exist in all three states of matter.

Answer 8

yes! at very very very high temperatures
