how do i solve this?

For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S
of the system, decrease S, or leave S unchanged. If you don't have enough information to decide, check the "not enough information" button in the last column.
Note for advanced students: you may assume ideal gas and ideal solution behaviour.
