L1 is the initial length of the material. DV g V o DT. V volume of unit m 3 ft 3 m mass of unit kg lb The change in the units volume when temperature changes can be expressed as.
Delta V V V_0 tag11 By replacing 11 in 10 we can calculate the final volume after thermal expansion function of the initial volume temperature difference and linear thermal expansion coefficient.
D V c v c V 0 t 1 t 0 where vc is the coefficient of volumetric expansion of the material of the container V0 is the internal volume of the container at an initial temperature and t1 t0 is the temperature difference. AA 2aL a A 2 a L. DV a v DT V 0. Where DV is the change in volume c V is the coefficient of volumetric thermal expansion of the material in K-1 3 times the coefficient of linear thermal expansion V init is the initial volume and DT is the change in temperature in Kelvins.
