LAb Report: Striking It Rich

Lab Report Purpose:         The purpose of this lab test was to fix ab place the different densities of different kinds of metal. We expend pennies made out of different metals to determine this. After we advance the data, itll be habituate to determine the metal utilise. Hypothesis:         In the lab, I extend that the pennies before 1982 would be heavier than those that ar aft(prenominal) 1983 because the metal was ab initio changed because the earlier pennies cost to a greater extent(prenominal) to make. So I consider that since the heavier metal was more expensive to make, hence they alone used a cheaper metal. So if the metal was heavier it may consent been more expensive to manufacture. Procedure: 1. Choose either to use Pre-1982 or Post-1983 to start the experiment. Find the mass with the weight plate and then record it onto the data table. 2. work 5 more pennies of the like kind then record the weight again. 3. put out t o retell step 2 until you weighed each 25 pennies on the scale. 4. subscribe to the 50 mL graduated cylinder to 20 mL of piss. Use the meniscus to measure the urine level. 5. With the 25 pennies used before, drop 5 pennies into the water, and record the new water level. 6. Add 5 pennies again and record the new water level. 7. ring Step 6 8.

Repeat Step 6 until every 25 the pennies are dropped into the graduated cylinder and alone the garishnesss are recorded. 9. Dry the pennies and store them or give them to the teacher. 10. Do the equal with the other set of pennies. 11. Find the net volume of both(prenom inal) set of pennies. (Subtract 20 mL from t! he total volume). 12. Enter all in all data into specific columns. Data and Observations: Data- 22mL-20mL = 2mL, 24mL-20mL = 4mL, 26mL-20mL = 6mL, 27.5mL-... If you want to get a full essay, order it on our website: BestEssayCheap.com
