STANDARD Physics Stefan's Law MCQ Question
Type: MCQ-numerical-Medium-Class 11
The rate of cooling at 600 K, if surrounding temperature is 300 K is H. The rate of cooling at 900 K is
A
16/3 H
B
2H
C
3H
D
2/3 H
Correct Answer
Option A
Detailed Explanation
By Stefan's law, the rate of cooling is proportional to (T⁴ - T₀⁴). Calculating for 900 K and 600 K, we find the rate at 900 K is 16/3 times that at 600 K.
