As a liquid is heated, its vapor pressure increases until the vapor pressure
equals the pressure of the gas above it.
Bubbles of vaporized liquid (i.e., gas) form within the bulk liquid and
then rise to the surface where they burst and release the gas. (At
the boiling temperature the vapor inside a bubble has enough pressure to
keep the bubble from collapsing.)
In order to form vapor, the molecules of the liquid must overcome the forces
of attraction between them.<span>
The temperature of a boiling liquid remains constant, even when more heat
is add.</span></span>
<span>In the event that you investigate where Chromium is on the intermittent table, it is one electron far from having 5 electrons in its 3d-subshell and a more prominent general strength. Consequently, with a specific end goal to accomplish this more attractive state, one of the 4s electrons is elevated to the 3d sub shell, accomplishing the half-full orbital and bringing about just a single electron staying in the 4s (valence) shell. Copper does this too.</span>
