WebThermal Expansion in Three Dimensions The relationship between volume and temperature d V d T is given by d V d T = β V, where β is the coefficient of volume expansion. As you can show in Exercise 1.60, β = 3 α. This equation is usually written as Δ V = β V Δ T. 1.4 Note that the values of β in Table 1.2 are equal to 3 α except for rounding.
