is it possible that if i have a cabin which is insulated from outside but is built with some sort of material like copper and there is a heating element of sort which is providing 100C constantly but because room is totally insulated and shut can the temperature goes upto 1000C or not ? if it is what kind of material can be used other can copper ?

  • $\begingroup$ define "totally insulated"?what material? thickness... $\endgroup$

  • $\begingroup$ Insulated by thick layers of mud, from every side and thickness of mud around the cabin would be at least 9 inch. $\endgroup$

  • $\begingroup$ The internal temperature will stabilise when the energy input is equal to the energy losses from the outside of your cabin : top, bottom and sides... $\endgroup$

  • $\begingroup$ Any particular material which losses less energy to outside meaning more and more heating should be inside? $\endgroup$

    $\begingroup$ What you want isn't called a "cabin". Look up "oven". $\endgroup$ Nov 6, 2017 at 12:45

If the heating element is constantly at 100°C, there is no way it can cause the room can get warmer than 100°C.

Otherwise, perpetual motion machines would be possible.

If you meant the heating element is providing a constant 100 Watts, then it is possible for the room to get to 1000°C with enough (meaning a lot) of insulation.

Your copper building might weaken to the point of collapse at 1000°C because copper melts at 1083°C.

    $\begingroup$ @Davidweb one way to think about this is the 100c heating element would be a cooling element for any room temperature above 100c. $\endgroup$

To answer the question the way it's asked

heating element of sort which is providing 100°C constantly but because room is totally insulated and shut can the temperature goes upto 1000°C or not ?

No, this is not possible. A 100°C heater can't heat its surroundings above 100°C. Heat will not pass from cold part of the system to hot part of the system. Heat passes only from a hotter to a colder system. First law of thermodynamics.
