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.

Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high pressure vapor
Which type of pressure system typically causes severe weather?
Low pressure
What atmospheric pressure causes hurricanes?
Hurricanes form from areas of low atmospheric pressure.
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 boiling point of water in space?
The boiling point of a liquid is the temperature where the vapor pressure is equal to the atmospheric pressure. Vapor pressure increases with temperature, as you heat the water up the vapor pressure keeps increasing until it matches the atmospheric pressure, then it is boiling. Space isn't quite a perfect vacuum, so the boiling point wouldn't be 0, but it would be very very low.
What causes cool temperatures of water vapor?
Water vapor can exist at low temperatures (below 100 °C = 132 °F) only if pressure is very low.
What is the state of refrigerant entering the compressor of a refrigeration system?
low temperature low pressure vapor
Is refrigerant leaving a compressor in a cars air conditioning system high pressure vapor high pressure liquid or low pressure vapor?
high 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 causes increases in barometric pressures?
Low and high pressure systems. Obviously if you have a Low pressure system the barometric pressure will get low. High pressure causes the barometric pressure to rise.
Refrigerant enters a compressor as a low pressure vapor?
Yea
What state is refrigerant entering the compressor?
Low pressure vapor
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.
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
