The density of water at \(20^\circ \text{C}\) is \(998\) kg/m3 and at \(40^\circ \text{C}\) is \(992\) kg/m3. The coefficient of volume expansion of water is:
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. \(10^{-4} / ^\circ\text C\)
1. \(3 \times 10^{-4} / ^\circ\text C\)
2. \(2 \times 10^{-4} / ^\circ\text C\)
