**EXPERT ANSWER**

# Problem 3: An equation for the heat capacity of carbon (solid) was given in an article as Cp = 1.2 + 0.0050 T – 0.0000021 T2 where C, is in Btu/(lb)(°F) and T is in °F. The calculated value of the enthalpy for C at 1000°F is 1510 Btu/lb. What is the reference temperature for the calculation of the enthalpy of carbon?
