Oxygen is contained in a piston-cylinder system initially at atemperature of 40 oC and a pressure of 150 kPa. Thepiston is 1 m in diameter and initially 20 cm above the base of thecylinder. Heat is added at constant pressure until the piston hasmoved 30 cm, so it's now at 50 cm.
I found the mass of the system to be 0.2898 kg, and T2 =783K.
a) Using the table of properties of oxygen as an ideal gas,calculate the heat added to the system per unit mass, in kJ/kg
b) Repeat this calculation assuming that the specific heat as afunction of temperature is linear over this range of temperatures(ie, assuming the change in temperature is \"small\")
c) Repeat this calculation without this assumption (ie, directintegration of empirical relation)
