MCQ
Under steady state, the temperature of a body
- AIncreases with time
- BDecreases with time
- CDoes not change with time and is same at all the points of the body
- ✓Does not change with time but is different at different points of the body
✓
Answer
Correct option: D.
Does not change with time but is different at different points of the body
(d) In steady state there is no absorption of heat in any position. Heat passes on or is radiated from it's surface. Therefore, in steady state the temperature of the body does not change with time but can be different at different points of the body.
