A Carnot heat engine has an efficiency of 0.200. If it operates between a deep lake with a constant temperature of 293.0 K and a

Dimas [21]

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

$\eta = 1-\frac{T_{o}}{T}$

Inserting the values

$0.200 = 1-\frac{293.0}{T}$

T = 366 K
