A metal ball immersed in alcohol weighs `w_(1) " at" 0^(@)C " and" w_(2) " at " 59^(@)C`. The coefficient of cubical expansion of the metal is less than that of alcohol. Assuming that the density of the metal is large compared to that of alcohol, it can be shown that

Explanation

`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`.
