Question

Two liquids $A$ and $B$ are at ${20}^{\circ }C$ and ${50}^{\circ }C$ respectively. When equal masses of them are mixed together, the temperature of the mixture becomes ${26}^{\circ }C$. The ratio of specific heat capacities of $A$ and $B$ is

• A. $3:1$
• B. $5:1$
• C. $2:1$
• D. $4:1$

Answer 1

The correct option is D $4:1$

$\frac{S_A}{S_B}=\frac{(50-26)}{(26-20)}$
$\frac{S_A}{S_B}=\frac{4}{1}$
