🔍 Key Concepts

• Behavior of refrigerants in closed cylinders (what changes with temperature and what does not) • Difference between mass (amount of substance) vs. volume, pressure, and temperature • How technicians meter or charge refrigerant into a system in practice

💭 Think About

• If the cylinder warms up or cools down, which of the four choices will definitely change, and which will stay directly tied to the actual amount of HCFC‑123? • Which of these (volume, weight, saturation temperature, saturation pressure) depends on the shape/size of the container rather than the amount of refrigerant? • In real-world servicing, what do mechanics actually use to know how much refrigerant they have put into or removed from a system?

✅ Before You Answer

• Recall that saturation pressure and saturation temperature for a refrigerant mainly track temperature, not directly how many pounds of refrigerant are in the cylinder. • Ask yourself which property is a direct measure of quantity of substance (mass), independent of container shape. • Think about standard practice: cylinders are often placed on a scale during charging—what property is being monitored?
