1. three liquids and four solids are placed in a graduated cylinder. the substances arrange themselves in the cylinder according to densities. use the information below to identify the liquids and solids in the graduated cylinder. start with the top solid as substance a, and the top liquid as substance b, and so on.

substance	density (g/cm³)
gold	19.3
water	1.00
gasoline	0.67
mercury	13.6
aluminum	2.70
cork	0.21

a.
b.
c.
d.
e.
f.
g.

Explanation:

Step1: Understand density - float relationship

Less - dense substances float on more - dense substances.

Step2: Arrange substances by density in ascending order

Cork (0.21) < Gasoline (0.67) < Oak wood (0.71) < Water (1.00) < Aluminum (2.70) < Mercury (13.6) < Gold (19.3)

Step3: Match to labels

The least - dense solid is cork (substance A), the least - dense liquid is gasoline (substance B), oak wood is substance C, water is substance D, aluminum is substance E, mercury is substance F, and gold is substance G.

Answer:

A. Cork
B. Gasoline
C. Oak wood
D. Water
E. Aluminum
F. Mercury
G. Gold
