A 50.0 g sample of liquid water at 25.0 °C is mixed with 19.0 g of water at 87.0 °C. The final temperature of the water is ________°C.

Question

Quizplus · Accepted Answer

The final temperature can be calculated using the principle of conservation of energy, where the heat lost by the hot water equals the heat gained by the cold water. Solving the equation (m1*c*(Tf-T1) = m2*c*(T2-Tf)) gives a final temperature of approximately 42.1°C.
