1. Bell-ringer: 7 minutes
What did the scientist do wrong in the following procedure?
A Scientist wants to test the vapor pressure (ability to "boil") of two liquids. He suspects the pressures will become equal at different temperatures. One is distilled water, the other is distilled water with 50 grams of salt added.
A liter of each liquid is put into each of two pans that happen to be handy: the distilled water is put into one that is cast iron, the salty water is put into an aluminum pan. The pans are set on the same size burners on a gas stove and two identical mercury thermometers are used.
It is found that the solution without salt boiled slowest and needed much more heat to do so. However these results were not in agreement with previous experiments, which said that salty water takes longer to boil, but when it does so, it boils at a higher temperature.
What changes would you make to revise the experiment?
