Boiling point is the temperature at which vapour pressure of liquid becomes equal to the atmospheric pressure. More is the vapour pressure lesser will be the heat require to raise its vapour pressure . So more is the vapour pressure lower is the boiling point .
point of water d. Pressure cookers keep water in a gas phase. The boiling of a substance is known as a phase change or phase transition. ... This source can be a hot surface or even the liquid itself. ...The boiling point of water is 100 Â°C (212 Â°F) at standard pressure.... [ boiling of water is higher in a pressure cooker because there is greater pressure within the cooker. ].he boiling of a substance is known as a phase change or phase transition. ... This source can be a hot surface or even the liquid itself. ... The boiling point of water is 100 Â°C (212 Â°F) at standard pressure.
