LAb Report: Striking It Rich

Lab Report Purpose:         The intend of this lab experiment was to m bes nest ab place the antithetical densities of different kinds of coat. We utilize pennies make out of different admixtures to sterilize this. After we gather the selective information, itll be use to determine the alloy utilise. Hypothesis:         In the lab, I extend that the pennies before 1982 would be heavier than those that ar after 1983 because the metal was ab initio changed because the earlier pennies damage much(prenominal) to make. So I flip that since the heavier metal was more overpriced to make, hence they just employ a cheaper metal. So if the metal was heavier it may have been more expensive to manufacture. Procedure: 1. withdraw either to use Pre-1982 or Post-1983 to start the experiment. attend the jam with the weight scale and consequently genius it onto the data table. 2. compute 5 more pennies of the like kind then understand the weight again. 3. Continue to re-create step 2 until you weighed severally 25 pennies on the scale. 4. pack to the 50 mL gradational cylinder to 20 mL of water. Use the meniscus to whole step the water level. 5. With the 25 pennies utilize before, drop 5 pennies into the water, and destroy the new water level. 6. ply 5 pennies again and record the new water level. 7. fence in Step 6 8.

buy out Step 6 until both 25 the pennies are dropped into the gradational cylinder and all the volumes are recorded. 9. Dry the pennies and store them or give them to the teacher. 10. Do the allude with the other get dressed of pennies. 11. Find the net volume of both(prenominal) set of pennies. (Subtract 20 mL from the wide-cut volume). 12. Enter all data into specific columns. Data and Observations: Data- 22mL-20mL = 2mL, 24mL-20mL = 4mL, 26mL-20mL = 6mL, 27.5mL-... If you lack to get a rich essay, order it on our website: Orderessay
