What causes the high surface tension and low vapor pressure of water?
Wiki User
∙ 11y ago
Hydrogen bonding causes the inward force that minimizes the surface area of water, and the tendency of water molecules escaping this bond to become vapor is slim and/or slow, thus creating it's low pressure.

Relation between atmospheric pressure and boiling point?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
Vapor pressure is measured when a liquid and its vapor are?
The pressure exerted by the gas in equilibrium with a solid or liquid in a closed container at a given temperature is called the vapor pressure
The difference between vapor pressure of a pure solvent and its partial pressure?
vapor pressure of a pure solvent is the pressure needed for the gas to escape the pure solvent in vapor form. its partial pressure in this case will be the pressure of that escaped vapour (in the mixture of air). in simpler terms vapor pressure describes a single condensable system (just the vapor of the solvent and the liquid state of the solvent) while its partial pressure describes the multicomponent system (air). they are essentially the same thing describing different systems
Explain why vapor pressure increases as temperature increases?
Vapor pressure increases as temperatures increase because water will evaporate in hot weather. This evaporation rises increasing the vapor pressure. This is why many areas have high humidity in the summer.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the boiling point. Evaporation is when vaporization of an uncontained liquid occurs.
How does vapor pressure of water change when a salt is added?
it decreases the surface tension of the water.
How concentration affect surface tension?
As the strength of intermolecular forces(IMFs) increases, vapor pressure decreases. This is because when IMFs are stronger it is harder for the compound to go to the gas phase, this means that the pressure the compound is exerting on the surrounding environment is lower.
Water has several unique properties such as high boiling point high surface tension and low vapor pressure The type of attraction that best accounts for these unique properties is?
hydrogen bonding
What is affected by surface water vapor and temperature?
air pressure
What causes particals to evaporate and leave the surface of a liquid?
Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)
What causes vapor pressure of a liquid?
The evaporation of the liquid by heating.
What effect does increase water vapor have on atmospheric pressure?
it causes a decrease in atmosperic pressure A+
When vapor pressure equals atmospheric pressure at the surface of a liquid it has reached its what?
boling takes place
What is affected by surface elevation water vapor and temperature?
air pressure
What is the affected by surface elevation water vapor and temperature?
air pressure
Are variables in evaporation?
For evaporation from a pure water surface, the rate of evaporation is proportional to the difference in vapor pressure between that of the water surface and that of the bulk air over it. The vapor pressure of water in turn depends on its temperature.
The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
