Your science teacher makes a density column using 3 of the following 5
liquids. | Designation | Substance | Density | | Liquid 01 | Honey | 1.5 g/mL | | Liquid 02 | Coca Cola | 1.1 g/mL | | Liquid 03 | Water
| 1.0 g/mL | | Liquid 04 | Motor Oil | 0.9 g/mL | | Liquid 05 | Corn Syrup | 1.4 g/mL | | | |
If he poured in the liquid from
the table with the greatest density and the liquid with the least density, which liquids would be
located a levels A and C?a. | Level A: Water
Level C: Coca Cola | c. | Level A: Honey
Level
C: Corn Syrup | b. | Level A: Honey
Level C: Motor
Oil | d. | Level A: Motor
Oil
Level C: Honey |
