Question:
The formula for Newton’s law of cooling is
Show Hint
In Newton’s law of cooling, Tₛ represents the surrounding temperature, Tₒ is the initial temperature, and k is a constant specific to the object.

T(t) = (Tₒ - Tₛ) e^kt
T(t) = Tₛ + (Tₒ - Tₛ)
T(t) = Tₛ + (Tₒ - Tₛ) e^kt
T(t) = Tₛ + (Tₒ - Tₛ) e^kt
Hide Solution
Verified By Collegedunia
The Correct Option is
D
Solution and Explanation
Newton’s law of cooling states that the temperature of an object is determined by the surrounding temperature and the difference between them. The correct formula is T(t) = Tₛ + (Tₒ - Tₛ) e^kt.
