Answer:
366 K
Explanation:
T₀ = Constant Temperature of deep lake = 293.0 K
T = Temperature of hot reservoir connected to carnot engine = ?
η = Efficiency of Carnot engine during the operation
Efficiency of Carnot engine is given as
[tex]\eta = 1-\frac{T_{o}}{T}[/tex]
Inserting the values
[tex]0.200 = 1-\frac{293.0}{T}[/tex]
T = 366 K
