Question
A metal ball immersed in water weighs w1 at 5oC and w2 at 50oC. The coefficient of cubical expansion of metal is less than that of water. Then
Options
A.w1 > w2
B.w1 < w2
C.w1 = w2
D.data is insufficient
Solution
w1 = Mg − FB
w2 = Mg − FB
= Mg − FB[1 + (γm − γl)ᐃT]
Since , γm < γl
So , w2 > w1 .
w2 = Mg − FB
= Mg − FB[1 + (γm − γl)ᐃT]
Since , γm < γl
So , w2 > w1 .
