The constant-pressure specific heat of carbon dioxide has been measured over the range of pressures and temperatures from ambient conditions to 1000 pounds per square inch gage and 1000 degrees F using a steady-flow calorimeter operating on an open cycle. It appears that the apparatus as used in this determination will yield values with a probable error of 0.5 percent at the highest temperature level considered.
