What is the boiling point of water at 100 psi?
| Absolute pressure | Water boiling point | |
|---|---|---|
| [bara] [1×105*Pa] | [psia] | [°C] |
| 1.013 | 14.7 | 100 |

| 1.103 | 16.0 | 102 |
At what point does water boil at atmospheric pressure?
100° C
The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).
How does hydrogen bonding affect the boiling point of water?
Hydrogen Bonding and Boiling Point The greater the attractions, more energy is needed and hence higher will be the boiling point. In water because of the hydrogen bonding attraction between molecules greater energy is needed to separate them from against their inter molecular attraction, therefore higher boiling point.
What happens at the molecular level when water is warmed to the boiling point?
Boiling Point Definition: Eventually the molecular motion becomes so intense that the forces of attraction between the molecules is disrupted to to the extent the molecules break free of the liquid and become a gas. At the temperature of the boiling point, the liquid turns into a gas.
How does molecular geometry affect boiling point?
Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. Molecular shape is also important, as the second group of compounds illustrate.
How do you find the boiling point of atmospheric pressure?
If the boiling point values for a specified substance at a specified BP temperature and pressure are given, one can determine the Boiling Point at different vapor pressure values using the Clausis-Clapeyron Equation. The Clausis-Clapeyron Equation is derived from VP2=VP1e−ΔHvRT at two different temperatures.
What is the boiling point of water at 12 psi?
At standard pressure the boiling point of water is 100 °C (212 °F)….Theory.
| Gauge Pressure (rel. to sea level) | Temperature | Appr. Cooking time (compared to boiling) |
|---|---|---|
| 0.7 bar (10 psi) | 116 °C (241 °F) | 33\% |
| 0.8 bar (12 psi) | 117 °C (243 °F) | 31\% |
| 0.9 bar (13 psi) | 119 °C (246 °F) | 27\% |
| 1.0 bar (15 psi) | 121 °C (250 °F) | 23\% |
How do atmospheric pressure and elevation affect boiling point?
At increasing altitude, atmospheric pressure declines. At a higher elevation, the lower atmospheric pressure means heated water reaches its boiling point more quickly—i.e., at a lower temperature. Water at sea level boils at 212 degrees Fahrenheit; at 5,000 feet above sea level, the boiling point is 203 degrees F.
Why does water boil when vapor pressure equals atmospheric pressure?
When any substance in the liquid phase, at atmospheric pressure, it means that this pressure is sufficient to confine the molecules together to form liquid. The molecules should possess equal energy to overcome this pressure for the liquid to boil.
What do you think will happen if hydrogen bonding in water does not exist at all?
Without hydrogen bonds, water molecules would move faster more rapidly, with less input of heat energy, causing the temperature to increase more for each calorie of heat added. This would also greatly reduce the amount of heat energy needed for phase changes from ice to liquid, and from liquid to vapor.
Why do hydrogen bonds have low boiling point?
H-bonds are a special case of an electrostatic interaction involving a hydrogen atom that is bonded to a very electronegative atom (typically oxygen or fluorine) and an electronegative atom that has lone pairs of electrons. Because there are fewer H-bonds to break, they have lower boiling points.
