Question
A room is initially at the same temperature as the air outdoors, 10°C. A heater which
consumes 1kW of electricity is switched on inside the room. If the exposed surface
area of the room is 30m^2 and the convection heat transfer coefficient from the
outside of the room to the surroundings is 6 W/m^2.°C, calculate the equilibrium
temperature reached in the room, assuming that the heater is 95% efficient. Neglect
any heat transfer out of the room by conduction and radiation
