A metal ball immersed in alcohol weights...

A metal ball immersed in alcohol weights `W_1` at `0^@C` and `W_2` at `50^@C`. The coefficient of expansion of cubical the metal is less than that of the alcohol. Assuming that the density of the metal is large compared to that of alcohol, it can be shown that

`gamma_M lt gamma_l`
So, `(F'_B)/(F_B)=([1+gamma_SDeltatheta])/([1+gamma_lDeltatheta])impliesF'_B lt F_B`
So apparent weight increased and `W_2 gt W_1`.
