Question

When a body that is conducting heat is under a steady state condition, then the temperature of the body

• A. Increases with time
• B. Decreases with time
• C. Does not change with time and is same at all the points of the body
• D. Does not change with time but is different at different cross-sections of a body

Answer 1

Answer: (D)

Does not change with time but is different at different cross-sections of a body

In steady-state, there is no absorption of heat at any position. Heat passes on or is radiated from its 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.
