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.
The rate of evaporation is influenced by the nature of the liquid through factors such as intermolecular forces, surface tension, and vapor pressure. Liquids with weaker intermolecular forces and higher vapor pressure tend to evaporate faster compared to liquids with stronger intermolecular forces and lower vapor pressure. Additionally, liquids with lower surface tension may also evaporate more rapidly.
The vapor pressure of a warm lake is higher than that of a cold lake because higher temperatures increase the kinetic energy of water molecules, causing them to evaporate more easily and increase the pressure of water vapor above the lake's surface.
The vapor pressure deficit formula is used to calculate the difference between the actual vapor pressure and the saturation vapor pressure in the atmosphere. It is calculated by subtracting the actual vapor pressure from the saturation vapor pressure.
Water vapor condenses at higher elevations because the air pressure decreases as altitude increases. This lower air pressure causes the water vapor to cool and condense into liquid water droplets, forming clouds or precipitation.
To calculate the vapor pressure deficit (VPD), subtract the actual vapor pressure (e) from the saturation vapor pressure (es) at a given temperature. The actual vapor pressure can be calculated using the relative humidity (RH) and the saturation vapor pressure can be determined from the temperature. The formula is VPD es - e, where es saturation vapor pressure and e actual vapor pressure.

When salt is added to water, the vapor pressure of water decreases. This is because the presence of salt disrupts the ability of water molecules to escape into the gas phase, lowering the overall vapor pressure of the solution.
When the vapor pressure equals atmospheric pressure at the surface of a liquid, it has reached its boiling point. This is the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on it by the surrounding atmosphere, causing the liquid to change into vapor.
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.

Molecules at the surface of a liquid absorb kinetic energy (kinetic energy used to disrupt intermolecular forces) and evaporate. (vapor pressure is exerted)
Boiling point
Above the surface of liquid water is a layer of water vapor. It has pressure. The atmosphere also has pressure. It pushes against the water vapor. The water vapor pushes against the atmosphere. It is called vapor pressure. It is related to temperature. When the vapor pressure equals barometric pressure, water boils. Normally this occurs at 100C or 212F. If you reduce the barometric pressure, you can reduce the boiling point of water. So when the barometric pressure is lower, the water vapor above the water has an easier time mixing with the atmosphere. As it mixes with the atmosphere, it is replaced by vapor from the water. It evaporates.
The energy that causes seawater to form water vapor is heat from the sun. When the sun's energy heats up the surface of the ocean, it causes water molecules to evaporate and rise as water vapor.
