A horizontal cylinder is separated into two sections by an adiabatic, frictionless piston.
One section contains 0.2 m3 of nitrogen and the other section contains 0.1 kg of helium.
Both gases are initially at 20?C and 95 kPa. The sides of the cylinder and the helium end
are well-insulated. Heat is added to the nitrogen section from a reservoir at 500?C until
the pressure in the helium section rises to 120 kPa. Assume constant specific heats for
both gases.
(a) What is the final temperature (?C) of helium gas?
(b) Determine the final volume (m3) of nitrogen gas.
(c) Calculate the amount of heat transfer (kJ) to nitrogen gas.
(d) How much entropy is generated (kJ/K) during the process?
