CRN 10938 Your Name Susan Chappell

DUE DATE: January 29, 30, or 31, 2019 TA’s Name __________________________

Please write your answers legibly in the space provided.

1. What is the intensive physical property studied in this lab experiment? What is the definition

Density; Intensive physical properties are independent of amount.

2. What is special about a balance?

It’s a scale that measures mass

3. What are the 3 steps for using a balance?


Tare the balance, place object on pan, record the mass and units



4. What should we know about the zero at the end of the measurement 9.990 g?

It is significant

5. What are the three devices used to measure liquid volume in this experiment, their smallest
graduation, and the place you will estimate to (and report)?




Buret- 0.1ml, 0.01ml
Graduated cylinder- 0.1 or 1ml, 0.01 or .1ml
Beaker- 25 or 10ml, 1ml


6. What gives rise to uncertainty?

estimation

, 7. What is the typical uncertainty in a measurement? Give the volume example and the mass
example shown in the video.

8. What are the two types of solids we can obtain volume for?

Regular and irregular solids

9. How do we obtain the volume of a regular solid?

A ruler and math equations

10. Who was the Scientist that gave us the method for determining the density of irregular
solids? What is that method called?


Archimedes; archimedes’ principle of dsiplacement


11. And what was his famous utterance? What does that word translate into?


Eureka- Ive got it

12. How do we calculate the volume of an irregular solid using Archimedes’ Principle? (Draw
the labeled graduated cylinder as part of your answer.)



D=m/v




13. Show the calculation we did in the video to determine the per cent of students wearing EKU
apparel in class that day.

6/53=11.32%
