A group of college students in a chemistry lab are asked to find
the maximum mass density of an unknown liquid between 0oC
and 40oC.
After they performed the experiment multiple times at different temperature,
they determined the volume is a function of temperature. They summerized
the formula to calculate the volume v of 1
kg at temperature
t. It is
v = 999.87 - 0.06426T + 0.0085T2 -
0.00006T3
