Calculate the change in entropy at constant pressure P when onemole of liquid water at 100 c is brought into contact with 1 moleof liquid water at 0 C. assumer that the heat capacity of liquidwater independent of temperature and is equal to 75 J / mol K. Noheat is lost to the surroundings.

So I'm not sure how to do this. I cant use the entropy of mixingequation because T is chaning, right? Then would it just beDeltaS =nCpln(T2/T1) + nCpln(T2/T1)... ??

Thanks for the help!
