Linear expansion coefficient: f-block
The coefficient of linear thermal expansion is the ratio of the change in length per degree K to the length at 273 K.
The coefficient of volume expansion is about three times the linear coefficient. The value of the coefficient is temperature dependent. See literature references for data at other temperatures
If l0 is the length at 273 K, alpha is the coefficient of linear thermal expansion, then the length at temperature t is given by:
lt = l0(1 + alpha.t)
