A sinker of weight `w_(0)` ha an apparent weight `w_(1)` when weighed in a liquid at temperature `t_(1)` and `w_(2)` when weighed in the same liquid at temperature `t_(2)`. The coefficient of cubical expansion of the material of the sinker is `beta`. What is the coefficient of volume expansion of the liquid?

Text Solution

Verified by Experts

The correct Answer is:
`(W_(0)-W_(1))/(W_(0)-W_(2))beta`
