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.

What is a brief description of the basic refrigeration cycle?
Starting at the compressor;Low pressure vapor refrigerant is compressed and discharged out of the compressor.The refrigerant at this point is a high temperature, high pressure, superheated vapor.The high pressure refrigerant flows to the condenser by way of the "Discharge Line".The condenser changes the high pressure refrigerant from a high temperature vapor to a low temperature liquid and leaves through the "Liquid Line".The high pressure refrigerant then flows through a filter dryer to the Thermal Expansion valve or TXV.The TXV meters the correct amount of liquid refrigerant into the evaporator.As the TXV meters the refrigerant, the high pressure liquid changes to a low pressure, low temperature, saturated vapor.This saturated vapor enters the evaporator and is changed to a low pressure dry vapor.The low pressure dry vapor is then returned to the compressor in the "Suction line".The cycle then starts over.
The conversion of a liquid to a vapor when the vapor pressure of the liquid equals the atmospheric pressure?
its boiling
What explodes under low pressure?
Anything expandable/flexible will expand under low pressure. but in order for it to explode I guess you need to contain it within a relatively thin container made of stronger material. eg. balloon
A pure solvent has a vapor pressure the vapor pressure of a solution A.EQUALTO B.LOWER THAN C.higher than?
A solution has a higher vapor pressure than a pure solvent. This is why salt water boils faster than pure water.
Explain how the attractive forces between the particles in a liquid and the equilibrium vapor pressure of that liquid related?
The weaker the intermolecular forces, the easier the liquid evaporates. Higher vapor pressure the faster it evaporates. Thus, the weaker the attractive forces, the higher the vapor pressure and vice versa.
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 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
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

What is the vapor pressure of KCl?
The vapor pressure of KCl depends on temperature. At room temperature (around 25°C), the vapor pressure of KCl is very low, close to negligible. As the temperature increases, the vapor pressure of KCl also increases, following the general trend for solids.
Why is alcohol used in manometer?
Manometer is a device that is being used to measure pressure. It uses alcohol because it has a low vapor pressure.
