Heat required to raise 1 kg carbon dioxide from -100 degrees C to -50 degrees C.
I arrived at an answer of 654,657 Joules.
I used the following: CO2-solid spec heat = 815 J/kgC
CO2-vapor spec heat = 2 J/kgC
sublimation point of 573,100 J/kgC
CmT(at -100C) plus sublimation point plus CmT(with temp change of 28.5C)
or 81,500 J + 573,100 J + 57 J = 654,657 J
Please let me know if this is correct, and if not, what I need to do to find the correct answer.
The sublimation point of carbon dioxide is -78 degrees C
This solution provides a solution for finding heat required to raise 1 kg carbon dioxide from -100 degrees C to -50 degrees C.
