Webb1. The Shomate equation for the constant pressure heat capacity of a substance is given by Op = A + Bt+Ct² +D+* + Elt? where t = T/1000, T being the temperature in degrees Kelvin, and the heat capacity is in units of J/K mol. The constants. A through E, have specific values for a given compound and a particular temperature range.
