Question
Explain the term ‘steady state’.
✓
Answer
When one end of a metal rod is heated, the heat flows by conduction from hot end to the cold end.
- As a result, the temperature of every section of the rod starts increasing.
- Under this condition, the rod is said to be in a variable temperature state.
- After some time, the temperature at each section of the rod becomes steady i.e., does not change.
- Temperature of each cross-section of the rod now becomes constant though not the same. This is called steady state condition.
