PASSAGE
A thermometer, at an initial temperature of
10°C, was placed in a 20°C liquid. As the
temperature of the thermometer increased, it was
recorded every second over a 10-second period.
This procedure was repeated using a 30°C liquid
and a 40°C liquid. (See Figure 1.)

Next, the same thermometer, but at an initial

temperature of the thermometer was recorded every
