Question

Two liquid A and B are at ${32}^{o}C$ and ${24}^{o}C$. When mixed in equal masses temperature of mixture is found to be ${28}^{o}C$, Their specific heats are in the ratio of

• A. 3:2
• B. 2:3
• C. 1:1
• D. 4:3

Answer 1

The correct option is C 1:1

Since on mixing equal parts of both substances we reach the midpoint of the two temperatures, we can conclude that the specific heats of both substances are the same.
Hence the ratio is 1:1
