## Homework Statement

## Homework Equations

## 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 ?
