← ScienceWhich outcome impairs the Carnot cycle when internal friction increases?
A)Reduced work efficiency during expansion✓
B)Increased isothermal heat transfer rate
C)Elevated peak operating pressure
D)Decreased thermal reservoir temperature
💡 Explanation
Increased internal friction causes irreversibilities that lower efficiency because energy is lost to heat rather than converted to work during expansion. Therefore, less useful work occurs, rather than enhanced temperature differentials with thermal reservoirs or altered pressures.
