Specific Heat Coefficients (SphUp0, SphUp1, SphUp2, SphUp3 and SphLo0, SphLo1, SphLo2, SphLo3)

Parameter Variable and Physical Definition

Temperature-Dependent Specific Heat Coefficients: The coefficients determined to determine the relationship between specific heat and temperature through a third order polynomial, seen below.
