As a 1.00 cm diameter plunger reduces the height of the column of air inside the chamber from 7.00cm down to 0.50cm, the temperature inside increases from 20C to 210C. Determine the air pressure inside the chamber (in atm) after compression if the initial air pressure is 1.0 atm. Assume the air is comprised of a series of ideal gases.
