～～Temperature VS Volume～～
What is/are the formula(e) that illustrate(s) the relationship between temperature and volume of a liquid of mass m?
Please in terms of whatever necessary to the formula (e.g. specific heat capacity, surrounding pressure, heat coefficient).
Thanks a lot~

The formula is:
V2 = V1[1+.C.(T2-T1)]
where V1 is the original volume of the liquid (in metre cube) at temperature T1(in unit of K or deg.C); V2 is the new volume at temperature T2.
C is the coefficient of volume expansivity (or cubic expansitivity) of the liquid.
For water, C is not a constant but depends on temperature. It takes the value of 0.53x10^-4 K^-1 at 5-10 deg.C, 1.5x10^-4 K^-1 at 10-20 deg.C... etc.
e.g. if 5 mL of water at 5 deg.C is heated to 10 deg.C, the new volume is,
V(new) = 5x[1+0.53x10^-4(10-5)] mL = 5.001325 mL

specific heat capacity= E=mcΔT
