Physics-Newton's Law of Cooling

NEET Physics Newton's Law of Cooling MCQ Question

Type: MCQ-diagram based-Hard-Class 11

Consider a graph showing the cooling of a hot body over time with the temperature difference (∆T = T2 - T1) on the y-axis and time (t) on the x-axis. Which of the following options correctly describes the nature of the curve as predicted by Newton's Law of Cooling?

Question diagram
A

The curve is initially steep and becomes less steep over time.

B

The curve is a straight line with constant slope.

C

The curve is initially flat and becomes steeper over time.

D

The curve is an exponential growth curve.

Correct Answer

Option A

Detailed Explanation

The graph shows that the rate of cooling is higher initially and decreases as the temperature of the body falls, consistent with Newton's Law of Cooling.
