HW 41.5

Postby Prasanna Padmanabham 4I » Tue Feb 11, 2020 8:10 pm

Hello, I am really stuck on this problem. I would super appreciate it if someone could please help me solve it.

4I.5

Suppose that 50.0 g of water at 20.0 8C is mixed with 65.0 g of water at 50.0 8C at constant atmospheric pressure in a thermally insulated vessel. Calculate ΔS and ΔS (total) for the process.

Thank you!

So first, you set q(hot water) = -q(cold water) to find the temperature at equilibrium. Then you use the S = Cln(T2/T1) subbing in the Temperature at equilibrium to find the change in entropy for the hot and cold water individually, before you add them together to find the total entropy change
