(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

1 Kg of water is heated at 0 degree C is brought into contact with a large heat reservoir at 100 degrees C. When the water has reached 100 degrees C, what has been the change in entropy of the water? And of the heat reservoir ? what has been the change in the entire system consisting of both water and the heat reservoir?

2. Relevant equations

[tex]\Delta[/tex]S_{w}= mcln(T_{f}/T_{i})

where

m = mass of water

c = specific heat capacity of water ( 4186 J/K)

T_{f}= final common temperature of water and the reservoir

T_{i}= initial temperature of water (and also reservoir for part b of the question)

3. The attempt at a solution

The application of formula above gave me answer for entropy change in water but not for reservoir and the whole system. Some help anticipated.
