Can metals turn to gas?

Q. An ideal diatomic gas is enclosed in an insulated chamber at temperature

300

K

. The chamber is closed by a freely movable massless piston, whose initial height from the base is

1

m

. Now the gas is heated such that its temperature becomes

400

K

at constant pressure. Find the new height of the piston from the base.
If the gas is compressed to initial position such that no exchange of heat takes place, find the final temperature of the gas.

Think of the metals as highly stable molecules, that are tightly bound together. When subjected to high temperature and pressure all metals melt. This is how utensils and other appliances are formed in the industries. Increasing the temperature and reducing pressure will lead to gaseous state for all metals. But as the previous answer states you need to contain the gaseous metal somewhere. That vessel should not melt at that temperature and pressure etc. So in principle all metals can be made to be in vapor state.

A typical example of such phenomena is the CFLs, and Sodium Vapor lamps. In Sodium vapor lamps as the name dictates has Sodium present in gaseous state.
