Lab: Density of Solids

Question 1

Which circumstances could be sources of error within the experiment? Check all that apply.not fully submerging the object when doing the fluid displacement procedurewater that is left behind in the collection container when it is transferred for measurementwater that soaks into the materials of the balls, affecting the mass in repeated trialsthe time of day when the measurements are recordedwater in the bucket, approximated to the closest 10 mL due to surface tension at the top of the bucketthe air pressure in the room and its affect on the scales that measure the mass of each object

Revolt · Accepted Answer

not fully submerging the object when doing the fluid displacement procedure; water that is left behind in the collection container when it is transferred for measurement; water that soaks into the materials of the balls, affecting the mass in repeated trials; water in the bucket, approximated to the closest 10 mL due to surface tension at the top of the bucket

Question 2

Throughout the reflection, make sure you have a copy of the Student Guide, PDF or Word, and your data tables. Use the drop-down menus to complete the statements.

✔ density; In all three parts, the dependent variable was .: density; The independent variable is the one that the scientist intentionally manipulates. In Part I involving the golf ball and table tennis ball, the independent variable was .: mass; In Part II involving the inflated and deflated footballs, the independent variable was .: volume; In Part III involving the baseball, the independent variable was .: material
