The Attempt at a Solution
Coefficient of volume expansion γ = ∆V/V∆T
VT2 = constant
Differentiating we get ,
T2∆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 ?
