I solved the problem, but I can't get the right unit for the answer.
A Carnot engine whose low-temperature reservoir is at 16°C has an efficiency of 31%. By how much should the temperature of the high-temperature reservoir be increased to increase the efficiency to 70%?
My numerical answer is 544.8. I tried Kelvin first - the most obvious choice - but that was wrong. Then I tried celcius and J/K.
I tried to work it out but I have no earthly idea - the other choices include:
- C0 (like the celcius sign but the circle is after the C)
-J/kg*K
-J/mol*K and
-kJ/kg
Any help would be grately appreciated.
