Chemistry Charles's Law Post-Laboratory Questions
1. Serveral students performed this experiment without payingadequate attention to the details of the procedure. Briefly explainwhat effect each of the following procedural changes would have ontthe size of the volume-to-temperature ratio calculated by thestudents.
A) One student failed to replenish the boiling water in theboiling-water bath as the flask was being heated. At the end of the6 min of heating, the boiling water in the bath was only in contactwith the lower portion of the flask.
B) Following the proper heating of the flask in the boilingwater, a student removed the flask from the boiling-water bath butonly partially immersed the flask in the ice-water bath during thecooling period.
C) A student neglected to close the pinch clamp before removingthe flask from the boiling-water bath and immersing it in theice-water bath.
D) One student neglected to measure the volume of the flaskbefore leaving the laboratory. Because the procedure called for a125-mL Erlenmeyer flask, the student used 125 mL as the volume ofthe flask.
