I am currently strugling as to why the entropy of a Reservoir, is defined as the heat transfered to said reservoir divided by the temperature of said reservoir. Such that:
Since that the integration of the fundamental expression of Thermodinamics will give the change in entropy as:
Under the assumption that the gas in the reservoir is an ideal monoatomic gas.
In my understanding since the volume and the temperature of the reservoir remain constant, during the heat tranfer process, this would imply that the change in entropy would be zero. How does this correlate with
I must be doing something wrong :(
I apolagize in advance, if there are any grammar or spelling errors. My english is getting rusty.
