Answer to Question #155113 in General Chemistry for YT _

Question

In Charles Law experiment, there are directions in the Procedure, which if not followed, would introduce ERRORS. Consider the Deviations below, AND comment on H-O-W a student's RESULTS would be affected if: 1.) A student allowed all the water in the beaker to boil away, but continued the experiment. 2.) Another student was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing. 3.) A student used the measure of Flask no.1 to be 250mL, without measuring the volume as directed. 4.) A student recorded the temperature in degrees Celsius and used these values in the calculations.

Answer 1

Deviations will affect the experiment in this way:

1) The temperature will go toward room temperature.

2) The temperature would decrease because it will try to equalize with the temperature in the room.

3) If the volume was not measured, the volume would affect the results of the experiment if flask volume is incorrect.

4) The calculations will be incorrect because the temperature must be expressed in kelvins.
