When a liquid turns to a vapor a change of physical state occurs. The liquid atoms are in constant motion according to the kinetic theory. The constant motion transfers kinetic energy between the atoms. When atoms gain enough kinetic energy they will move and bounce to far that they have enough energy to overcome the attractive forces which are holding them to the liquid. They escape as a vapor.
The energy may come from an outside source such as the room temperature. If the room temperature is higher than the liquid temperature a thermal exchange will occur. This thermal energy will cause the atoms to gain energy faster and the change of phase will occur quicker.

The liquid bromine evaporates to form a gas, and then the air molecules in the gas jar keep bumping into them, changing their direction so that they eventually fill the whole jar.
