Newton Cooling

1) Study the rate of heat loss from a hot object placed in a cooler medium over time. 2) verify Newton's Law of Cooling and measure the cooling constant k in practice.
Newton's Law of Cooling states that the rate of change of an object's temperature is directly proportional to the difference between the object's temperature and the temperature of its surroundings, provided this difference is relatively small.

  1. Set the initial temperature T₀ using the first slider (range: 30–100 °C).
  2. Set the ambient temperature T_env using the second slider (range: 0–40 °C). Make sure T₀ is greater than T_env.
