6.1 Density

Question 1

What is density

Answer 1

The density of a substance is defined as its mass per unit volume

Question 2

Equation for density, mass and volume. To work out density

Answer 2

density = mass/volume

Question 3

How do you measure the mass of an object

Answer 3

electronic balance

Question 4

How can you tell if an object will float on water by their density

Answer 4

objects that have lower density than water float in water

Question 5

how to find volume of solid

Answer 5

measure dimensions multiply together

Question 6

how to find density of small irregular solid

Answer 6

• Measure mass on a balance and record
• Fill displacement can with water
• Lower object slowly using string
• Collect water displaced in a measuring cylinder
• Displaced water volume is volume of object
• Density = mass/volume
• Repeat three times and calculate mean

Question 7

how to measure volume of liquid

Answer 7

measuring cylinder

Question 8

how to measure density of regular object

Answer 8

• Measure mass with balance and record
• Measure length width and height of object with a ruler
• Do the lenght x with x height to work out volume
• Density = mass/volume
• Repeat three times and calculate mean

Question 9

mass units for density equation

Answer 10

kg

Question 11

volume units for density equation

Answer 11

m cubed
