The following errors in procedure will affect the experimental result. Explain how wach action causes an incorrect result. 1) Student A was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing. 2) Student B used the measurement of Flask no. 1 to be 250mL, without measuring the volume directed. 3) Student C recorded the temperature in degrees Celcius and used these values in calculations. 4) Water remained on the outside of the flask and on the foil when the final mass was determined.

The following errors in procedure will affect the experimental result. Explain how wach action causes an incorrect result.

1) Student A was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing.

2) Student B used the measurement of Flask no. 1 to be 250mL, without measuring the volume directed.

3) Student C recorded the temperature in degrees Celcius and used these values in calculations.

4) Water remained on the outside of the flask and on the foil when the final mass was determined.

 

action causes an incorrect result. Procedure (part A): Student A was in a hurry and stopped heating, even though bubbles were still emerging from the rubber tubing. 1) 2) Student B used the measurement of Flask no. 1 to be 250 mL, without measuring the volume as directed. 3) Student C recorded the temperature in degrees Celsius and used these values in the calculations. Procedure (part B): 4) Water remained on the outside of the flask and on the foil when the final mass was determined.
