## Question

A metal ball immersed in alcohol weighs *W*_{1} at 0^{0}C and *W*_{2} at 59^{o}C. The coefficient of cubical expansion of the metal is less than that of alcohol. Assuming that the density of metal is large compared to that of alcohol, it can be show that:

### Solution

The upthrust is given by

So the upthrust at t^{o}C is given by

As hence upthrust at *t *^{o}C < upthrust at 0^{o}C. So the upthrust is decreased. Hence, weight in liquid gets increased.
