Two equal bodies with temperatures T1 and T2.
T1 > T2. The specific heat c does not depend on temperature.
What is the maximal work which can be done from this system?
I have to get equation for max work which includes c and temperatures.
This seems to be rather simple problem, but it has been very difficult for me so far to understand the concepts and judgments behind this problem. So could someone please help me?
The Attempt at a Solution
I know that we have to make a system.Where one body is the heater and other is cooler.
So i know:
The heat from heater dQ1=T1dS1
and cooler dQ2=T2dS2
goes to reservoir where work is done
Offcourse i know that change in entropy is equal to
The next step should be to establish that max work is equal to
and further use the carno cycle efficiency coefficient
Do not have any idea how to do it keeping in mind the previous relations :(
