1. DENSITY OF MATTERS

2. Same the number of car
Different the width of road
Same road
The number of car is different
The number of car = mass
The width of road = volume

3. Density is mass in the unit volume
d= mass/ volume = g / cm3

4. Which liquid is denser than other ?
Olive oil
Pure water
Which liquid is denser than other ?

5. Post Laboratory Work dpurewater < degg.
INFERENCES
A. Part 1
The location of egg did not change according to the amount of water. The egg always sinking on pure water. The amount of water does not affect the location of egg.
Thus,
dpurewater < degg.
B. Part 2
When salt is added into water, the egg is floating. Therefore, salt- water mixture is denser than egg’ density.
dsalt-water > degg.
Hence, location of egg or ships depends on the density of
dpurewater<degg<dsalt-water
dpurewater<dsaltwater
