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 filling a charging cylinder the refrigerant that is vented off the top of the cylinder?
Must be recovered

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

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 is meant by restricting liquid refrigerant into a refrigeration system when charging?
Vaporizing the refrigerant
Why is the gauge line secured when the refrigerant cylinder is on the scale while transferring refrigerant?
The gauge line is secured when the refrigerant cylinder is on the scale while transferring refrigerant to prevent the refrigerant from leaking out. If the refrigerant were to leak out, it would cause the scale to become inaccurate, and it would also be a safety hazard.
What is meant by restricting liquid refrigeration system when charging?
Vaporizing the Refrigerant
What is charging of a compressor?
It means charging the A/C system with the proper kind and amount of refrigerant + oil. Overcharging the system will damage the compressor.
What is a reason to obtain an accurate pressure reading of refrigerant inside a recovery cylinder?
Damaged refrigerant
