Answer 2

Mass is measured in g or kg

Question 3

What is volume?

Answer 3

Volume is the amount of space that an object takes up

Question 4

What is volume measured in?

Answer 4

Volume is measured in ml, cm3 or m3

Question 5

What is density?

Answer 5

Density is the amount of matter per unit volume

Question 6

What is density measured in?

Answer 6

Density is measured in g/cm3 or kg/m3

Question 7

Density Formula (word)

Answer 7

Density = mass/volume

Question 8

Density Formula (symbol)

Answer 8

ρ=m/v

Question 9

Experiment to Find the Density of a Cube or Cuboid

Answer 9

1. Find the mass of the solid using a balance
2. Measure the length (l), width (w) and height (h) of the object
3. Calculate the volume of the object (V= lxwxh)
4. Calculate the density using the formula: ρ=m/v

Question 10

Experiment to Find the Density of Irregular Shaped objects

Answer 10

1. Find the mass of the solid using a balance
2. Fill the Eureka Can to the brim with water
3. Place a measuring cylinder below the spout of the Eureka Can
4. Drop the object into the Eureka Can, the displaced water will come out of the spout
5. The volume of water displaced is equal to the volume of the solid
6. Find the density of the solid using the equation: ρ=m/v

Question 11

Experiment to Find the Density of Liquids

Answer 11

1. Find the volume of the liquid using a measuring cylinder
2. Find the mass of the empty measuring cylinder using a balance
3. Find the total mass of the measuring cylinder plus the liquid using a balance
4. Subtract the mass of the empty measuring cylinder from the total mass. This will give you the mass of just the liquid
5. Find the density of the liquid using the formula: ρ=m/v
