Question

A well-insulated cup of water is too hot to make tea, so you mixed it with an equal amount of cool water to lower the temperature. The temperature of the mixture is exactly the midpoint between the temperature of the hot and cool water. What is the entropy change of the system consisting of the total amount of water

Answer 1

The entropy of the final solution decreases, as the reaction disorder is less.

Step-by-step explanation:

The higher the temperature, the greater the heat of the reaction and the greater the disorder it has, so the entropy will increase ... But this is not the case, since the solution cools, decreasing the entropy proportionally.
