Enter values for the initial and ambient temperatures and the value of k (note that this will need to be found from other information such as a second known time-temperature pair). Slide the red point along the x-axis, noting the time and temperature. What does the y-intercept represent? What is happening to the slope of the tangent as time increases? What is happening to the temperature as time increases? When has the temperature decreased by half the initial temperature?
What happens if you enter an initial temperature that is lower than the ambient temperature?
