SUMMARY
The coefficient of volume expansion (γ) for gases is defined by the equation γ = ∆V/V∆T, where ∆V is the change in volume, V is the initial volume, and ∆T is the change in temperature. The discussion confirms that the coefficient is variable and inversely proportional to temperature, as indicated by the derived relationship ∆V/V∆T = -2/T. The negative sign signifies that volume decreases with increasing temperature in this scenario. Therefore, the correct interpretation is that the coefficient of volume expansion is negative, affirming that as temperature rises, the volume of the gas contracts.
