A temperature probe is placed in a container of icewater, as seen in the photograph below. At the left is a digital timer, measuring elapsed time in seconds, in the center is the thermal probe, measuring the temperature of the icewater bath in degrees Celcius, and at the right is the 1000 ml beaker of icewater with the thermal probe.
Now 50 ml of salt is poured into the icewater, the timer started, and the thermal probe used to mix the salt into the icewater, as seen in an mpeg video by clicking your mouse on the photograph above.
The question is: What will happen to the temperature of the icewater as time goes on?
