Class Notes: Finding Volume with Displacement Sept. 8, 2023

  1. Displacement - a method of determining volume by measuring the amount of fluid displaced (moved out of place) when the object is submerged in it.

    • Used of objects that have irregular shape and cannot be calculated using geometric formulas.

    • Calculated: Vobject = Vfinal - Vinitial

      • Vo = Vf - Vi

  2. Lab Method

    • Start with a graduated cylinder.

    • Fill it with enough water to cover the object

      • do not put the object in yet!

    • measure the volume of water very carefully

    • put in the object

    • remeasure the volume of the water and the object.

    • calculate in FDSS format using the formula above.


POP Quiz - open notes

Lab Exploration - displacement



Due tonight:

  1. When finished, research this link from AZEK - I think this is probably the manufacturer of the PVC trim board these samples were cut from because Home Depot sells it and I bought the board at Home Depot. Prepare a report that:

    1. summarizes the results of your density measurements of the white blocks.

      • Do this in a table with 2 columns and five rows. The columns should be titled for the sample number and its calculated density. Use the bottom row for the average density of all three samples.

    2. State the density specification for AZEK PVC Trim including proper units.

    3. Discuss whether your results are close enough to the specification for AZEK to confirm our samples are made of that material.

    4. Identify two other properties of AZEK (from its data table) and discuss why each property might be important to a builder that was considering AZEK trim for their construction business.

    5. Speculate - Why might a builder choose AZEK (PVC Plastic) trim instead of traditional wood?

    Prepare your report in Google Classroom.

    Be sure it has a proper heading and appropriate title at the top.

    Write in complete sentences and thoughts.

    Submit it NLT Friday at Midnight.
