DENSITY OF MATTERS

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

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

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

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
