A piston-cylinder device contains 0.85 kg R-134a at 263K. The piston is free to move and has a mass of 12 kg and diameter of 25 cm. The atmospheric pressure is 98 kPa. Heat is added to the cylinder until the R-134 temperature = 10 o C.
YOU DO NOT NEED TO INTERPOLATE. YOU CAN ROUND PRESSURE TO THE NEAREST kPa.
a. What is the final pressure?
b. What is the change in volume of the cylinder?
