The value of the coefficient of volume expansion of glycerine is \(5\times10^{-4}~\text{K}^{-1}.\) The fractional change in the density of glycerine for a rise of \(40^\circ \text{C}\) in its temperature is:
| 1. | \(0.015\) | 2. | \(0.020\) |
| 3. | \(0.025\) | 4. | \(0.010\) |
| 1. | \(3 \times 10^{-4} / ^\circ\text C\) | 2. | \(2 \times 10^{-4} / ^\circ\text C\) |
| 3. | \(6 \times 10^{-4} / ^\circ\text C\) | 4. | \(10^{-4} / ^\circ\text C\) |
