Under low pressure condition we can boil water at room temperature. Explanation: When we heat the water, the temperature of the water rises. Due to this the water molecule “gains kinetic energy” and starts to move and escapes to the atmosphere in the form of vapor. Water typically boils at 100°C when the pressure is equal to 1 atm, but when the pressure is reduced using a vacuum pump, the water boils at room temperature. When the pressure above a liquid is reduced, the vapor pressure needed to induce boiling is also reduced, and the boiling point of the liquid decreases.
