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.
Explanation / Answer
1.) As in Charle's law V/T remains constant only when no of molecules remains constant as water is boiling away so no. of molecules are nt same as before.
2.) Heating shouldn't be stopped otherwise how temp will be different for different volume.
3.) Volume should be measured in proper manner as directed otherwise Charle's law will not be valid.
4.) For Charle's law temp sholud be converted in Kelvin scale not in celsius scale.
