What is the change in the enthalpy, in kJ/kg, of oxygen as its temperature changes from 150 to 250°C? The constant-pressure spe heat of oxygen at room temperature is cp= 0.918 kJ/kg-K. Is there any difference if the temperature were to change from 0 to 100°C? Consider the variation of specific heat with temperature. cp = 0.964 kJ/kg-K at 200°C and cp= 0.934 kJ/kg-K at 100°C. The change in the enthalpy of oxygen is The difference between the first case and the second case is | |kJ/kg. |%.
