Newton’s law of cooling
Watch a hot body approach room temperature.
What to notice
The cooling rate falls as the temperature difference gets smaller.
Key relation
T − Ta = (T₀ − Ta)e^(−kt)
Try this
Compare the same hot body in two different surroundings.
What you can change
- Initial temperature: 60 to 100 °C
- Ambient temperature: 10 to 30 °C
- Cooling constant: 0.03 to 0.15 s⁻¹
