0.1 kg of air is contained in a spring-loaded piston-cylinder arrangement as shown in the figure below. The mass of the piston is 80 kg with a diameter of 20 cm. The piston is exposed to an atmospheric pressure of 101 kPa. Initially, the temperature of air is 300 K and the spring just touches the top of the piston. Heat is added until the spring is compressed to 18.0 cm. Neglect the effect of friction between the piston and cylinder and let the spring constant to be 30 kN/m. Determine: (a) The initial pressure of air inside the cylinder, in kPa (b) The final temperature of air, in K
