During early steam engine development, which limitation caused atmospheric engines to be less efficient than later designs?

A)Condenser heat loss during cycles✓

B)Piston friction reducing power output

C)Material fatigue limiting boiler pressure

D)Incomplete combustion increasing fuel use

💡 Explanation

In early atmospheric engines, the cylinder was cooled to condense steam, creating a vacuum; however, this cooling also lowered the cylinder temperature, causing significant heat loss during subsequent heating cycles. Therefore condenser heat loss limited efficiency, rather than friction, fatigue, or combustion which relate to different engine components and inefficiencies.
