1.	One litre of water at 40°C is mixed with one litre of water at 50°C. The temperature of the mixture will be:
Answer» ANSWER: the temperature will SLIGHTLY less than 40°C. Explanation: Because WATER expands when heated, 1 litre of water at 50°C will have less mass than 1 litre of water at 30°C. As a RESULT, the 30°C litre has slightly more than the 50°C litre, and thus the average will end up slightly less than 40°C. Explanation:
