Question

A metal ball immersed in Alcohol weights W₁ at 0°C and W₂ at 50°C. The coefficient of cubical expansion of the metal (γ)_m is less than that of alcohol (γ)_Al. Assuming that density of metal is large compared to that of alcohol, it can be shown that

W₁ < W₂

W₁ > W₂

any of W₁ > W₂, W₁ = W₂ or W₁ < W₂

W₁ = W₂
