A cylinder of an ideal gas with an initial volume of 0.635 m3
, undergoes an adiabatic
compression. The initial pressure of the gas behind the piston is 1.01 x105 Pa, and its final pressure
is 2.95 x 105 Pa. The gas’s initial temperature is 373 K. If the final temperature of the gas is 573 K,
(a) How many moles of the gas are there?
(b) What is the final volume of the gas in the cylinder?
(c) If the process includes the input of 51,600 J of work on the gas, what is the change in the internal
energy of the gas?
