SUMMARY
The discussion focuses on calculating the amount of cold water needed to lower the temperature of a warmer water sample. The relevant equation is q = c * m * ΔT, where ΔT represents the temperature change. To achieve a final temperature of 50 degrees Celsius, the heat lost by 100 grams of 80-degree Celsius water must equal the heat gained by the unknown mass of 20-degree Celsius water. The principle of conservation of energy dictates that the heat lost by the warmer water is equal to the heat gained by the cooler water.
