Follow Up Questions Show all work for questions involving calculations. Part I Use the concepts/vocabulary of density to explain why the liquids formed layers in Part I of the procedure. (8 pts) The liquids formed layers because they all had different densities. The liquids with light density were towards the top of the layers. What was the control used during the liquid portion of Part I of this experiment (8 pts) (Hint What did you do the same with each liquid to ensure a fair comparison) The control used during the portion of part I was the amount of liquid used. Rank the following in terms of relative density (9 pts) Isopropyl alcohol (rubbing alcohol) lowest relative density Liquid dishwashing detergent- intermediate relative density Dark corn syrup-high relative density Vegetable oil-second lowest relative density (intermediate) Glycerin-second highest relative density Rubber stopper- second highest relative density Cork stopper- low relative density (ended up with the alcohol Wood- low relative density (ended at the top with the rubber alchohol. Lead- highest relative density Part II (7 pts each) In Part II, what happened to the cans of soda when you placed them in water Use the concepts/vocabulary of volume and mass to explain the final positions of the cans in the sink full of water. The diet soda floated in the water while the regular soda sank. The regular soda had a higher relative…

    Labratory Techniques and Measurments

    Part 1: After reading the various information given, I gathered different objects and measured them using both centimeters and millimeters then converted them to meters. Next, I recorded the temperature of hot tap water and boiling water as well as cold tap water and ice water in Celsius and converted them to Fahrenheit and Kelvin. I then gathered a few other objects and placed them on the scale measuring for mass in grams and converted them to kilograms.…
