Volume expansivity of a pure substance is given by

(a) \(\beta=-\frac{1}{V}\left(\frac{\partial V}{\partial T}\right)_{P}\)

(b) \(\beta=\frac{1}{V}\left(\frac{\partial V}{\partial T}\right)_{P}\)

(c) \(\beta=V\left(\frac{\partial V}{\partial T}\right)_{P}\)

(d) \(\beta=\frac{1}{V}\left(\frac{\partial T}{\partial V}\right)_{P}\).
