Relative density and density

Density of an object is 2500 kg/m³. What is the relative density of the object when the density of water is 1000 kg/m³.

[Relative density = Density of substance/ density of water]

• 2.5

• 25

• 0.25

• 250

The density of water is ______kg/m³

• 1

• 10

• 100

• 1000

The amount of space an object takes up.

• mass

• volume

• density

• weight

As a substance is COOLED its DENSITY...

• increase

• decreases

• remains equal

The degree of compactness of a substance..

• mass

• volume

• density

• weight

 Jack has a rock. The rock has a mass of 14 g and a volume of 2 cm³. What is the density of the rock?

• 1/7 g/cm³

• 28 g/cm³

• 7 mL

• 7 g/cm³

The ability to sink or float.

• volume

• mass

• solution

• relative density

Why does the egg not sink or float?

• it is more dense than the water

• it is less dense than the water

• it has the same density as the water

• it is light

Rocks sink because they are

• the same density as the water

• less dense than the water

• more dense than the water

• because they're round
