density of materials

Question 1

What does the density of an object tell you

Answer 1

How many of its particles have been squished into a given space

Question 2

What is density

Answer 2

A measure of the compactness of a substance

Question 3

What are the units of density

Answer 3

Kg/(m)3

Question 4

How do you work out density

Answer 4

Mass/volume

Question 5

What does the density of an object depend on

Answer 5

What it’s made of and how its particles are arranged

Question 6

How does a dense material have its particles

Answer 6

Tightly packed together

Question 7

How are particles in a less dense material

Answer 7

More spread out

Question 8

What happens if you compress the material

Answer 8

Its particles would move closer and it would become more dense

Question 9

Put the three states of matter in order of density

Answer 9

Solids
Liquids
gases

Question 10

How do you find the density of a solid object

Answer 10

1)Use a balance to measure its mass
2) is its regular solid start by measuring its length width and height with a ruler
3) calculate the volume
4)You can find its volume by submerging it in a eureka can filled with water the water displaced by the object will be transferred to the measuring cylinder
5)Pluck the objects mass and volume into the formula to find the density

Question 11

How do you find the density of a liquid

Answer 11

1) Put a measuring cylinder on a balance and zero the balance
2) Put 10 mL of the liquid into the measuring cylinder and record the liquid mass
3)Put another 10 mils and repeat the process until the cylinder is full and record the total volume and mass each time
4)For each formula use the measurement to find the density
5)Take an average of your calculator densities
