← HistoryWhich outcome arises in early steam engines when the piston extensively cools the cylinder during expansion?
A)Reduced pressure increases overall efficiency
B)Increased wear from lubricant carbonization
C)Vacuum formation causes structural collapse
D)Condensation reduces the net work output✓
💡 Explanation
When the relatively cold piston cools the cylinder, isothermal expansion cannot be maintained, leading to condensation because the water vapor turns back into liquid, absorbing thermal energy. Therefore, condensation and reduced net work results, rather than increased pressure, increased wear, or structural collapse which rely on other mechanisms.
