Q: Coefficient of apparent expansions of a liquid in two different vessels are a and b. then the real coefficient of expansions of liquid, if the ratio of volume expansion of vessels is x : y

(a) $\displaystyle \frac{bx-ay}{x-y}$

(b) $\displaystyle \frac{ay + bx}{x+y}$

(c) $\displaystyle \frac{ay-bx}{x-y}$

(d) $\displaystyle \frac{ay+bx}{x-y}$

Ans: (a)
