A metal ball immersed in alcohol weighs W1 at 0∘C and W2 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 [1980]
a. W1>W2
b. W1=W2
c. W1<W2
d. None of these
