STANDARD Physics Heat Transfer MCQ Question
Type: MCQ-numerical-Medium-Class 11
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
A
18.2°C
B
22°C
C
20.3°C
D
24.2°C
Correct Answer
Option C
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.
