Acarnot engine has an efficiency of 23.9%. it operates between constant-temperature reservoirs differing in temperature by 68.8°c. in kelvins, what are (a) the temperature of the hot reservoir and (b) the temperature of the cold reservoir?

(a) 287.9 K

The efficiency of the engine is given by

where

Tc is the temperature of the cold reservoir

Th is the temperature of the hot reservoir

We can rewrite the two temperatures as

(because differences in Kelvin are equal to differences in Celsius)

So we can rewrite the 1st equation as

We also know the efficiency:

So we can re-arrange the previous equation to find the temperature of the hot reservoir:

(b) 219.1 K

The temperature of the cold reservoir can be found as:
