what is efficiency of carnot engine between the temperature of 100 degree centigrade and 60 degree centigrade

100 + 273 = Th

60 + 273 = Tc

100 * (Th-Tc)/Th

100+273=373

60+273=333

10.72%?

The efficiency of a Carnot engine can be determined using the formula:

Efficiency = 1 - (Tc/Th)

where Tc is the temperature of the cold reservoir and Th is the temperature of the hot reservoir.

In this case, the temperature of the cold reservoir (Tc) is 60 degrees Celsius, which is equivalent to 333.15 Kelvin. And the temperature of the hot reservoir (Th) is 100 degrees Celsius, which is equivalent to 373.15 Kelvin.

Now we can substitute these values into the formula to calculate the efficiency:

Efficiency = 1 - (333.15/373.15) ≈ 1 - 0.893

So, the efficiency of the Carnot engine between the temperatures of 100 degrees Celsius and 60 degrees Celsius is approximately 10.7%.
