When you have a hot drink, you know that it gradually cools off. Newton’s law of cooling provides us with a model for cooling. It states that the temperature difference Tdiff between a hot object and its surroundings decreases exponentially with time.
In the model T0 is the initial temperature difference, and k is a positive constant.
In this activity you will use a Temperature Probe to collect data as the warmed probe cools. You can then fit several mathematical models to the data.
Record temperature versus time cooling data.
Model cooling data with an exponential function.
