- Homework Statement
- A room 10mX10mX5m room is lighted by four 100 W lightbulbs. Assuming 73% of the energy is converted to heat, how much warmer will they room be in 6.9 hr. The room is insulated

- Relevant Equations
- dQ/dt=σAT⁴ radiation

I tried modeling the problem quite a few ways. one was to say that the difference between the heat emitted by the room and the heat emitted by the bulbs would equal the heat absorbed by the room, and that could allow us to calculate temperature. This did not work. I'd appreciate your help
