If the pressure is quickly reduced, the 221°F (105°C) water at normalpressure will now boil. For another example, put water at room temperature into a vacuum chamber and begin removing the air. Eventually, the boiling temperature will fall below the water temperature and boiling willbegin without heating.

Yes water boils at room temperature. Generally, boiling point of a liquid depends on inter molecular forces of
attraction. An input of energy is needed to give the molecules enough kinetic energy to break free from these forces.
The pressure above the liquid also determines boiling point. When the vapor pressure of the liquid is equal to the
external pressure, the liquid will boil. When the external pressure is lowered, so does the boiling point.
In order to make the water to boil at room temperature, the pressure above the liquid is reduced by a vacuum pump
(vacuum condition is maintained). Hence enough pressure is lost causing the water to boil.
