One end of a metal rod is placed in a furnace. Under steady-state conditions, the temperature of the rod
Options
- Aremains constant
- Bis nonuniform
- Cincreases
- Ddecreases
Correct answer
B. is nonuniform
Step-by-step solution
In steady-state heat conduction, the temperature at any specific cross-section of the rod does not change with time.
However, for heat to flow from the hotter end (in the furnace) to the colder end, a temperature gradient must exist along the length of the rod. This means the temperature decreases continuously as we move away from the furnace.
Since the temperature is different at different points along the length of the rod, the temperature distribution of the rod is nonuniform.
