Maximum efficiency = Carnot cycle

    Is it possible to show that the maximum efficiency for a heat engine is given by
    [tex]\eta = 1 - \frac{T_c}{T_h}[/tex]
    where [tex]T_c[/tex] is the temperature of the cold sink and [tex]T_c[/tex] is the temperature of the warm sink?

    In other words: How do I prove that a engine run by a Carnot cycle is the most efficient engine?

    can we take the efficiency of carnot cycle as 100%
    can we say that the efficiency of carnot cycle is 100%????

    No, we most certainly can't.
