Newton’s law of cooling is valid only for a
-
small temperature range
- large temperature range
- free flow range
- presence of heat source
The correct answer is: A
Explanation
Newton's Law of Cooling states that the rate of heat loss of an object is directly proportional to the difference in temperature between the object and its surroundings, provided that this temperature difference is small.
Therefore, this law is only valid within a small temperature range.
