the guy Posted July 4, 2011 Share Posted July 4, 2011 if there is a canister of CO2 at 1200 Ibf/in2 (8MPa) and the liquid CO2 is released into standard atmosphere pressure and temperature conditions, how much energy would it take for the CO2 to evaporate?

CaptainPanic Posted July 5, 2011 Share Posted July 5, 2011 The heat of evaporation of CO2 is 0.57*10^6 J/kg at atmospheric pressure at the boiling point (-78.5 °C). Note that the heat capacity of the solid (54.55 J/(mol K) at 189.78 K) is quite different from the heat capacity of the gas (33.89 J/(mol K) at –75°C).
