Newton's Law of Cooling

Predict the temperature of an object over time as it cools in a surrounding medium.

Final Temperature (T)
---°C
Object cooled by 100.00°C in 10 minutes.

The Physics of Cooling

Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature.

T(t) = Tₛ + (T₀ - Tₛ)e⁻ᵏᵗ

The constant k depends on the surface area, material properties, and the nature of the surrounding medium.
