🔍 Key Concepts

• Behavior of refrigerant and oil when mixed in a crankcase • What happens when pressure or temperature changes on startup or after shutdown • Difference between boiling out of solution, condensing, and viscosity changes

💭 Think About

• Think about what happens to refrigerant that is dissolved in oil when the compressor starts and the crankcase pressure changes suddenly. • Which of these options would actually create bubbles/foam inside the oil, rather than just making it thicker or thinner? • Consider what physical process produces visible foaming: is it liquid turning to vapor, vapor turning to liquid, or a change in thickness of the oil?

✅ Before You Answer

• Identify which choice directly describes gas/vapor bubbles forming inside the oil. • Eliminate any choices that would make the oil less likely to bubble or foam. • Check which option most logically happens right after startup of a refrigeration compressor that has been idle.
