Question:medium
Efficiency of Carnot engine is always:
Efficiency of Carnot engine is always:
Show Hint
An efficiency of $1$ ($100\%$) would violate the Kelvin-Planck statement of the Second Law of Thermodynamics.
Therefore, all real and ideal heat engine efficiencies are strictly less than $1$.
Therefore, all real and ideal heat engine efficiencies are strictly less than $1$.
