Description: Use this scenario: A pot of boiling soup with an internal temperature of 100° Fahrenheit was taken off the stove to cool in a 69° F room. After fifteen minutes, the internal temperature of the soup was 95° F. Use Newton’s Law of Cooling to write a formula that models this situation.

Key Concepts

Newton's Law of Cooling

Newton’s Law of Cooling is a principle stating that the rate at which an object's temperature changes is proportional to the difference between its current temperature and the ambient temperature. This concept is often applied in scenarios where an object is cooling or heating and forms the basis for creating models that predict temperature over time.

Differential Equations

Differential equations are equations that involve a function and its derivatives, describing how a quantity changes over time. In the context of cooling, a first-order differential equation is employed to mathematically represent the rate of change in temperature relative to the surrounding environment.

Exponential Decay

Exponential decay refers to the mathematical process where a quantity decreases at a rate proportional to its current value. When applied to cooling, it explains how the temperature difference between an object and its ambient temperature decreases exponentially, leading to formulations that capture the cooling behavior over time.

Initial and Boundary Conditions

Initial and boundary conditions specify the starting state of a system and the external influences acting upon it. In cooling problems, knowing the initial temperature of the object and the ambient temperature are crucial for determining the specific parameters in the cooling model and arriving at a unique solution.
