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.
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

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.
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.
Damaged refrigerant
The result of filling a recovery cylinder with iquid refrigerant and allowing it to warm up is that the heat of the container would warm the refrigerant inside of it. The refrigerant would, as a result expand.

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
