Transmission Of Heat Question 319
Question: If a rod is in variable state (not in steady state), then
Options:
A) temperature gradient remains constant
B) temperature of rod is changing with distance from one end and with time also
C) temperature of rod is not depending on time
D) temperature of rod is not depending on distance from one end
Show Answer
Answer:
Correct Answer: B
Solution:
[b] When rod is invariable state, then a part of heat energy is absorbed by a section of rod which increases internal energy (temperature) & remaining part is transferred to next section. Hence temperature of rod is changing with time as well as with distance from one end of rod.
