11.86 years, or around that time it would take about 12 years.
Answer:
T'=46.6 K
Explanation:
Let T be the temperature of a hot reservoir, T' be the temperature of cold reservoir.
For a Carnot's engine, efficiency can be calculated as follows:
Where, W is the amount of work done, Q is the amount of heat extracted from the hot reservoir.
Substitute the values: W= 8.0 J
Q = 10.0 J
T = 233 K
Thus, the temperature of the cold reservoir is 46.6 K.
