NEET Physics Newton's Law of Cooling MCQ Question with Solution

If the temperature of a body is 80°C and the surrounding temperature is 30°C, what is the rate of cooling according to Newton's Law of Cooling?

A

Proportional to 50°C

B

Proportional to 80°C

C

Proportional to 30°C

D

Proportional to 110°C

Correct Answer

Option A

Detailed Explanation
