A room is maintained at 20∘ C by a heater of resistance 20ohmconnected to 200voltmains. The temperature is uniform through out the room and heat is transmitted through a glass window of area 1 m2 and thickness 0.2cm. What will be the temperature outside? Given that thermal conductivityKfor glass is 0.2 cal/m/°C andJ= 4.2J/cal |
