Answer:

The thermal efficiency is defined as the ratio of the useful output energy (or work) to the input energy. Assuming these values represent temperatures and not the actual energy input and output, we can calculate the thermal efficiency using the Carnot efficiency formula:

Carnot efficiency = 1 - (T_low / T_high)

Where T_low is the temperature of the lower reservoir or heat sink, and T_high is the temperature of the higher reservoir or heat source.

Let’s calculateTo calculate thermal efficiency, we need to know the the thermal efficiency for the given scenarios:

input heat and the output work or heat. However, the information provided in the question is incomplete11. Thermal efficiency between 230K and 700K:

T_low. Please provide more details or specific parameters so that I can assist you in calculating the thermal = 230K

T_high = 700K

Carnot efficiency = 1 - (230 efficiency for each scenario.
