One end of a metal rod is kept in a furnace. In steady state, the temperature of the rod

Options

A. Increases
B. Decreases
C. Is uniform
D. is non uniform

Explanation

To solve the question about the temperature distribution in a metal rod with one end placed in a furnace, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have a metal rod with one end (let's call it end A) placed in a furnace, which is at a higher temperature (let's denote this temperature as \( T_H \)).
- The other end of the rod (let's call it end B) is at a lower temperature (denote this as \( T_L \)).

2. **Steady State Condition**:
- The term "steady state" implies that the temperatures at both ends of the rod have stabilized and are constant over time. This means that the temperature at end A is \( T_H \) and the temperature at end B is \( T_L \).

3. **Temperature Gradient**:
- Since one end of the rod is in contact with a heat source (the furnace) and the other end is cooler, there will be a temperature gradient along the length of the rod. This means that the temperature will change from \( T_H \) at end A to \( T_L \) at end B.

4. **Non-Uniform Temperature Distribution**:
- The temperature will not be the same throughout the rod; instead, it will vary between \( T_H \) and \( T_L \). Therefore, the temperature distribution is non-uniform.

5. **Conclusion**:
- Based on the analysis, we conclude that in steady state, the temperature of the rod is non-uniform.

### Final Answer:
The temperature of the rod is non-uniform.
