spherical vessels with Ar and Ne are connected through a valve. Assume now that the initial temperature of Ne is $600$ K$,$ while all other parameters, including pressures and temperature of Ar remain as shown. Neglect the volume of the connecting tube and assume that the diameter of each spherical vessel is $1$ m$.$ After the system has equilibriated, both vessels rest at $400$ Kelvin. What is the change in entropy in J$/$K$.*$The correct answer is $183\mathrm{.}87*$
