A system undergoes a two-step process. In the first step, the internal energy of the system increases by 229 J when 166 J of work is done on the system. In the second step, the internal energy of the system increases by 115 J when 169 J of work is done on the system. For the overall process, fine the heat added to the system (including sign).
