Which risk increases when a Carnot engine operates irreversibly?

💡 Explanation

Irreversibility increases exhaust heat because frictional losses within the system raise its entropy; therefore, less energy performs purposeful work in irreversible processes, rather than maintaining maximum efficiency according to Carnot's idealization.

• Which mechanism causes increased solubility in supercritical fluids?
• Which risk increases significantly when a metallurgical process approaches the Carnot efficiency limits?
• Which outcome occurs when moisture freezes within porous concrete during rapid cooling?
• After prompt criticality in a water-moderated reactor, which mechanism initially reduces the fission rate?
• Which mechanism limits spatial resolution when constructing STM topographic images from electron wave functions?
• Which outcome accelerates when a radioisotope thermoelectric generator's (RTG) shielding degrades?
