🔍 Key Concepts

• Behavior of water vapor when cooled in a distilling plant condenser • Effect of condensation on the specific volume of steam vs. liquid water • Influence of pressure changes (via valve J) on the volume of saturated vapor

💭 Think About

• When steam at low pressure enters the device labeled 24, what phase changes occur as it contacts the cooler tube surfaces? • How does the specific volume of saturated steam compare to that of condensed liquid water at the same pressure? • If valve J is opened too much, how would that change the pressure and what effect would that have on volume, according to basic gas laws?

✅ Before You Answer

• Identify that unit 24 is functioning as a condenser/heat exchanger for the water vapor coming from 23. • Recall that when vapor condenses to liquid, its volume changes by several orders of magnitude. • Check which option correctly links cooling + condensation with a decrease vs. increase in volume, and which options confuse cause and effect.
