🔍 Key Concepts

• Boiling point and pressure relationship • Definition of saturation in thermodynamics • Difference between saturated and superheated states

💭 Think About

• Which term is used when a liquid and its vapor can exist together in equilibrium at a given pressure? • Which option refers specifically to a temperature at which phase change (liquid to vapor) occurs? • How do the words "degree" and "temperature" change the meaning of the thermodynamic terms in the choices?

✅ Before You Answer

• Identify which choices describe a specific temperature value, not a range or amount of change • Separate terms related to phase-change conditions (liquid and vapor together) from those describing vapor above its boiling point • Verify which term is commonly paired with a given pressure on steam tables and refrigerant tables
