WebJun 6, 2024 · With any body of water, water molecules are always both evaporating and condensing. The vapor pressure of water is the pressure at which the gas phase is in … WebSo when water boils at 100 C at 1 atm, this means that only at 100 C does the vapour pressure of the water overcome the external vapour pressure. If you increase the external pressure to 2 atm, the water requires more energy to be able to overcome this pressure, therefore boiling point increases. this is how it works.

Boiling point - Wikipedia

WebVapor pressure (also known as equilibrium vapor pressure or saturated vapor pressure) is defined as the pressure exerted by a vapor in thermodynamic equilibrium with the condensed phases (solid or liquid) at a given temperature. At 100 o C, the vapor pressure of water is 1 atmosphere; i.e. 100 o C is the normal boiling point of water.

"WebFeb 22, 2024 · The temperature at which this occurs is called the boiling point. The vapor pressure of a liquid is a measure of how easily it vaporizes. The higher the vapor pressure, the easier it is for the liquid to turn into a gas. Liquids with high vapor pressures are often used as solvents because they evaporate quickly.

High vapor pressure and boiling point

WebA liquid will boil when its vapor pressure equals atmospheric pressure. Water’s normal boiling point is 100°C. At this temperature the vapor pressure of water is equal to 101 kPa, standard atmospheric pressure. If we were in a location with a different atmospheric pressure the boiling point would be different. WebSince the vapor pressure increases with temperature, it follows that for pressure greater than 760 mmHg (e.g., in a pressure cooker), the boiling point is above 100°C and for …
