7th edition 4I. 5

Postby Alyssa Bryan 3F » Sun Feb 17, 2019 11:01 pm

Suppose that 50.0 g of water at 20.0 C is mixed with 65.0 g of water at 50.0 C at constant atmospheric pressure in a thermally insulated vessel. Calculate delta S and delta S total for the process?
Why is there a difference between delta S and delta S total for this process?

The delta S refers specifically to the hot water and the cold water, and delta S total is the sum of delta S for the cold water and the hot.

There are two values for delta S (one for hot and one for cold), and delta S total is just the sum of the two delta S values.

Does anyone know what equation this is on the 6th edition?
