Cooling of a Cup of Tea (Newton's Law of Cooling)

This GeoGebra example dynamically simulates the cooling process of a cup of hot tea, showing the temperature-time curve that follows an exponential decay pattern. The core mathematical concept is Newton's Law of Cooling, which states that the rate of heat loss is proportional to the temperature difference between the object and its surroundings, leading to an exponential decay function. The construction uses GeoGebra text objects (texto1, texto2) to display temperature and time labels, likely combined with a function graph or slider to animate time progression, illustrating how temperature approaches ambient temperature. This is suitable for high school or college courses in physics and mathematics, particularly for teaching exponential functions, differential equations, or real-world modeling. It also serves as an interactive lab for students to adjust parameters and observe changes in cooling rate.
