Water molecules hydrogen bond which is a very strong intermolecular force. As a result the water molecules are held together well. Vapor pressure is dependent on how well molecules are intermolecularly bonded to one another. If a substance like water is held together well then it will have a low vapor pressure because a larger amount of energy is required to break these intermolecular bonds. Compare water to carbon tetrachloride which is non polar and can't hydrogen bond. Because it only has weak London dispersion forces to hold the molecules together it will have a higher vapor pressure. This is because only a small amount of energy is required to break the intermolecular bonds causing the CCl4 to vaporize.

What is the vapor pressure of lead?
The vapor pressure of lead is very low at room temperature and atmospheric pressure. Lead is a solid metal with a boiling point of 1749°C, so it is not typically found in a vapor state under normal conditions.
Increasing hydrogen bonding has what effect on vapor pressure of water?
Increasing hydrogen bonding in water leads to a decrease in vapor pressure. Stronger hydrogen bonds require more energy to break, making it harder for water molecules to escape into the vapor phase. As a result, fewer molecules enter the vapor phase at a given temperature, resulting in lower vapor pressure. This is why water has a relatively low vapor pressure compared to other liquids.
What atmospheric pressure causes hurricanes?
Hurricanes form from areas of low atmospheric pressure.
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
Refrigerant leaving a compressor in a car's air conditioning system is a high pressure, high temperature vapor. This vapor carries heat energy away from the evaporator coil inside the car, allowing the refrigerant to absorb heat from the cabin air and cool it down before circulating it back.
What does low pressure system cause the air around a tornado to do?
A tornado has low pressure in it, but it is not considered a low pressure system as it is too small to be its own weather system. The low pressure in a tornado causes the surrounding air to rush into it.
What is the state of refrigerant entering the compressor of a refrigeration system?
low temperature low pressure vapor
How the compressor working?
Refrigerant enters the compressor inlet as a low pressure vapor. The compressor increases the pressure, and discharges it as a high pressure vapor.
What does AC compressor do?
Cycles refrigerant through the system and changes the state of the refrigerant from a low pressure vapor to a high pressure vapor.
What state is refrigerant entering the compressor?
Low pressure vapor
Refrigerant enters a compressor as a low pressure vapor?
Yea
What is the Refrigerant entering the compressor of a refrigeration system is a?
low temperature low pressure vapor
What is low vapor pressure?
Vapor pressure refers to the force exerted by gaseous molecules of a liquid. Usually this is measured in a closed system. For example, in a water bottle some H2O molecules are able to move from liquid to gas phase at room temperature. The molecules that do this create vapor pressure. Low vapor pressure is usually observed in substances that have a low boiling point or if it is being held at a low temperature.
Does low tire pressure causes squeaking?
No. Low tire pressure causes poor handling and poor tire wear.
What is the state of refrigerant entering the compressor of the refrigeration system?
low temperature low pressure vapor
What is the state of the refrigerant entering the compressor of a refrigeration system?
low temperature low pressure vapor
What causes cool temperatures of water vapor?
Cool temperatures of water vapor are usually caused by the expansion of the vapor, leading to a decrease in temperature through adiabatic cooling. This can occur when water vapor rises in the atmosphere, expands due to lower pressure, and cools as it ascends. Additionally, the mixing of cooler air with warm, moisture-laden air can also cause the temperature of water vapor to decrease.
How is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with the vapor from a cylinder?
Add refrigerant vapor on the low side of the system ,the compressor raises the pressure of the refrigerant on the high side of the system and lowers the pressure on the low side
