Question

500 person seating capacity hall is insulated from 2 side of wall but rest wall are exposed to surrounding. Each person adding 10 KJ of heat in to the place at that same time 50 celling fan is operated which consume 20 KJ of work each. Certainly after some time 40 people left. During the interval coffee machine consume 100KJ. Apply the first law of thermodynamics and model the given case and find out net heat and work interaction.
