An ideal black body at room temperature is thrown into furnace. It is observed that
A furnace is a device used for heating or melting materials at high temperatures. It is commonly used in industrial processes like metal smelting, glass production, or for heating in buildings. Furnaces operate by burning fuel or using electrical energy to generate heat for various applications.
Chapter 10 of Class 11 Physics covers thermal properties of matter. It includes topics such as temperature and heat and thermal expansion and specific heat capacity and calorimetry. The chapter also explains heat transfer methods like conduction and convection and radiation. It further discusses laws of thermodynamics and ideal gas laws.

An ideal black body at room temperature absorbs all the incident radiations and therefore appears black. It begins emitting thermal radiation after heating in a furnace and then increases in brightness with increasing temperatures. An ideal black body would emit radiation dependent on its temperature and thus, be brightest when heated to its higher temperatures.
