1.0 L of water at 30°C is to be mixed with 2.0 L of water at 100°C, as in Exercise 1. Before mixing, however, the temperature of each moves half-way to 0 °C (so the 30°C water cools to 15°C). What is the temperature of the resulting mixture? Is this half the temperature of the result in Exercise 1?
The above are similar to examples of weighted averages with absorption.
