There is a container which has 3 ideal monoatomic gas molecules, named x, y, z. The number of molecules for X is Nx = 3, Ny = 2, and Nz = 4. The container volume is 12 units. First, determine the entropy of the system in units of Kb. Then, find the amount of heat exchange with the system, qsys, if the volume undergoes a reversible isothermal expansion to 18 units and the temperature is 300K.
