p1 - materials

Question 1

variables

Answer 1

independent - material being measured
dependent - density of the material
control variable - temperature

Question 2

to find density of a solid you needs:

Answer 2

a balance
a displacement can (eureka can)
measuring cylinder
beaker
solid

Question 3

finding volume of solid

Answer 3

set balance to 0

record name of solid and mass of solid

fill the eureka can with water until the water just starts to come out the spout

add solid to the eureka can

collect the water that comes out of the spout

amount of water displaced is the volume of solid

Question 4

density equation

Answer 4

density (g/cm^3) = mass (g) / volume (cm^3)

Question 5

to find density of a liquid you need:

Answer 5

a balance
a measuring cylinder
beaker
liquid

Question 6

how to find density of a liquid

Answer 6

set balance to 0 and then add the beaker

find the volume of your liquid by adding it to the measuring cylinder

add the liquid to the beaker and measure the mass using the balance
