How is the refrigerant cylinder pressure kept above the system pressure when charging with vapor from a cylinder?
The refrigerant cylinder is heated in a tub of water to no more than 90 degrees F. Electric heating blankets manufactured for this purpose may also be used.
What does the vapor pressure of water at 10 C compare with its vapor pressure at 50 C?
At higher temperature the vapor pressure is higher.
Is increase of vapor pressure a colligative property?
The lowering of the vapor pressure is a colligative property.
Which of the colligative properties is not dependent on vapor pressure boiling point elevation vapor pressure reduction osmotic pressure?
Osmotic pressure.
What statements is true about vapor pressure?
The vapor pressure of 1 m sucrose (C12H22O11) is higher than the vapor pressure of 1 m NaCl where the solvent is water Sea water has a lower vapor pressure than distilled water. The vapor pressure of 0.5 m NaNO3 is the same as the vapor pressure of 0.5 m KBr, assuming that the solvent in each case is water The vapor pressure of 0.10 m KCl is the same as the vapor pressure of 0.05 m AlCl3 assuming the solvent in each case is water The vapor pressure of 1 m NaCl is lower than the vapor pressure of 0.5 m KNO3, assuming that the solvent in each case is water The vapor pressure of 0.10 m NaCl is lower than the vapor pressure of 0.05 m MgCl2 assuming the solvent in each case is water.
Why does refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
When vapor refrigerant is pulled out of a cylinder the vapor is reduced and the liquid boils to replace the vapor that has left the cylinder.
When charging a system with vapor refrigerant from a refrigerant cylinder the cylinder will become?
Lighter, as the refrigerant is boiled off, and colder, as it has absorbed heat, and has a lesser pressure to reflect the current temperature / pressure relationship for the type of refrigerant

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.

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 is the refrigerant cylinder pressure kept above the system pressure when a system is being charged with vapor from the 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

Why does the refrigerant pressure decrease in a refrigerant cylinder while charging with vapor?
The reason is that as the liquid evaporates in the tank and it cools it down and the vapor pressure (pressure in tank) is reduced and the evaporation rate decreases. Many refrigeration repair men have a bucket big enough to put their tank in and add hot water to keep the tank warm and get the freon to evaporate faster to speed up their project.

Refrigerant enters a compressor as a low pressure vapor?
Yea
