Air is compressed in a cylinder from a pressure of 80 kPa and a temperature of

so that the volume occupies one quarter of the original volume while the temperature remains constant. Calculate: a) The final pressure of the air. b) The final temperature if the air is now heated to the original volume at the new pressure.
