A 50.0 g sample of liquid water at 25.0 °C is mixed with 23.0 g of water at 89.0 °C.The final temperature of the water is ________ °C.

Question

Quizplus · Accepted Answer

The final temperature can be found using the principle of conservation of energy, where the heat lost by the hot water equals the heat gained by the cold water. Since the specific heat capacity of water is constant and the mass and initial temperatures are given, the final temperature can be calculated to be within the range of the initial temperatures, making 45.2 °C the only plausible answer.
