3. The attempt at a solution

Coefficient of volume expansion γ = ∆V/V∆T

VT^{2}= constant

Differentiating we get ,

T^{2}∆V + 2VT∆T = 0

∆V/V∆T = -2/T

So , option 2) looks right . Is that correct ?

How do I interpret the answer ? Does that mean the coefficient is a variable and is inversely proportional to temperature ? What does negative sign signify ?
