We have 2 volumes of water at different temperatures. When they are mixed they will eventually exchange heat and come to the same temperature.
The heat absorbed by the cold water would be the same amount as the heat released by the hot water. Although the signs will be different because the direction of heat transfer is different. This can be represented by the equation below.
When 155 mL of water at 26°C is mixed with 75 mL of water at 85°C, what is the final temperature? (Assume that no heat is released to the surroundings; d of water = 1.00 g/mL.)
