Question

To improve the conduction of heat of the surface
A metal rod is heated to a temperature of 200°C. It is placed in a room at 30°C. At which temperature, the rod
will stop radiating heat?​

Answer 1

Answer:

The metal will stop radiating at 30C

Explanation:

I have friends here. It is given metal rod he did at 200°C. The temperature of the road is 200 Plus 2 73 Kelvin. That is 4 73 Kelvin. It is kept in a room having the temperature 30°C, that is 303 Calvin. So rod is kept in a room so energy is radiated per unit area per unit time. He's sigma. Hey temperature of the road To the power zero and temperature of surrounding to the powers. For when the temperature of the road becomes equal to temperature of the surrounding that is room. Then cuba upon T becomes zero. So or not it stops and meeting the radiation that is heat radiation. When temperature off the road becomes equal to temperature of the room that is at 30°C. That's not. Thanks for watching.
