The temperature outside is -10 C . You have a heat pump that can deliver 2kW of heat to your room. The only heat transfer occurs through a glass window which has an area of 5.1m2, a thickness of 1.3mm and a thermal conductivity of 0..8W/mK. Given that the room has no curtains, your room is otherwise well insulated and the outside temperature stays the same, what is the highest temperature that the room will reach.

A wall in a house contains a single window. The window consists of a single pane of glass whose area is 0.15 m2 and whose thickness is 1.9 mm. Treat the wall as a slab of the insulating material Styrofoam whose area and thickness are 15.00 m2 and 0.110 m, respectively. Heat is lost via conduction through the wall and the window. The temperature difference between the inside and outside is the same for the wall and the window. Of...
