STANDARD Physics Heat Transfer MCQ Question
The temperature of equal masses of three different liquids A, B and C are 12°C, 19°C and 28°C respectively. The temperature when A and B are mixed is 16°C and when B and C are mixed is 23°C. The temperature when A and C are mixed is
18.2°C
22°C
20.3°C
24.2°C
Correct Answer
Detailed Explanation
Using the principle of heat exchange and the given temperatures, we set up equations for the mixtures. Solving these equations gives the temperature when A and C are mixed as 20.3°C.
