The temperature in the deep interiors of some giant molecular clouds in the Milky Way galaxy is 50 K. Compare the amount of energy that would have to be transferred to this environment to the amount that would have to be transferred to a room temperature environment to bring about a 7.7 J/K increase in the entropy of the universe in each case.

What would happen to the entropy of a system if you could increase the
pressure without changing the temperature, volume, or number of
particles?
A box contains 100 gas molecules all released on the left side of the box. What is the initial entropy of all the gas molecules on one side?
You can calculate the number of microstates (left/right distribution of molecules) possible by the equation W = N! / ( nL! * nR!,) where N is the total number of molecules and nL is the number on the left and nR is the number on the right. What is the entropy of the most disorganized distribution of gas molecules?
