One is the apparent expansion coefficient and the other one is the real expansion coefficient. Length of the liquid before the change o temperature. L f Final length.

Suppose the length of a rod at 0 C is L 0 and at temperature θ measured in Celsius is L θ. Use the coefficient of linear expansion α for steel from Table 1 and note that the change in temperature ΔT is 55C. If the volumetric expansion coefficient does change appreciably with temperature or the increase in volume is significant then the above equation will have to be integrated.
