Question

If $S_1$ is the specific gravity of a solid with respect to a liquid and $S_2$ is the specific gravity of the liquid with respect to water, then the specific gravity of the solid with respect to water is :

• A. $S_1+S_2$
• B. $S_1$ $\times S_2$
• C. $S_1-S_2$
• D. $S_1/S_2$

Answer 1

Answer: (B)

$S_1$ $\times S_2$

$S_1=\frac{densityofsolid}{densityofliquid}$

$S_2=\frac{densityofliquid}{densityofwater}$

$\therefore$ specific gravity S of solid w.r.t water $=\frac{densityofsolid}{densityofwater}$$=S_1\times S_2$
