A typical incandescent light bulb wastes 90% of its power as heat. Ignoring the contribution of the walls and any furniture, if you left a 100 watt incandescent bulb on in a 5 by 5 by 5 meter room for 100,000 seconds, how much would the temperature of the air in the room increase, in degrees Celsius? Assume, for simplicity, that the room is a closed thermodynamic system, the heat capacity of air is 1 joule per gram per degree, and the mass density of air in the room is 1.2 kilograms per cubic meter.
