Energy can cross the boundaries of a closed system in the form of heat or work. For the reversible isothermal process, for the gas ΔS > 0 for expansion and ΔS < 0 for compression. ������k׽���XEb��Y���{\b�k���"�O֝�f��W�/��b }�� �_�ݿl��������erq�m\��Gj��jW�/x�W��f=|^$yvi�l����|��j��)8P�6��8�4���U�I/��^�EQiR�Ф#̻ Q is negative if heat leaves the system.
