Question 1

How do you calculate the density of a regular shape?

[3 points]

Answer 1

1) Measure the mass of the solid on scales
2) Measure the three lengths and calculate the volume
3) Calculate the density

Question 2

How do you calculate the density of a irregular shape?

[3 points]

Answer 2

1) Measure the mass on scales
2) Put into water and measure the amount of displaced water using a displacement can (this is equal to the volume, 1ml = 1cm^3)
3) Calculate the density

Question 3

1ml =

In cm^3

Answer 3

1cm^3

Question 4

How would do find the density of a liquid?

Answer 4

• Put into a measuring cylinder to find the mass
• Work out the volume from amount of ml

Question 6

What is a meniscus?

What does it mean for the practical?

Answer 6

• (From web) Water molecules are attracted to the molecules in the wall of the glass beaker. And since water molecules like to stick together, when the molecules touching the glass cling to it, other water molecules cling to the molecules touching the glass, forming the meniscus.
• When measuring how much water you have in a measuring cylinder, read from the bottom of the meniscus so your results are accurate.
