density of a material (Required Practical)

Question 1

what is a density of a material

Answer 1

mass for a given volume

Question 2

what is the equation to work out density

Answer 2

density = mass
——
volume

density=kg/m cubed

mass= kg

volume=m cubed

Question 3

how do you determine the densities of regular solid objects.

Answer 3

1. use a balance and find the mass of the object
2. then find out the volume of the object
3. then to work out density do mass divided by volume
   4.

Question 4

what is the difference between a irregular and regular shape

Answer 4

regular shaped can be easily measured using a ruler while irregular cant

Question 5

how do you determine the densities of irregular solid objects.

Answer 5

1. find the mass of the object using a balance
2. fill a eureka can with water
3. put the object in the water
4. This will cause water to be displaced and low out of the can through the spout.
5. measure the volume of the displaced water and use that volume in the formula to work out density
6. the formula for density is mass / volume
