density

Question 1

density equation

Answer 1

density = mass/ volume

Question 2

how do you measure the density of an irregular object

Answer 2

• find out the objects mass
• fill the eureka can with water just to the top of the spout
• place an empty beaker under the spout
• drop the object in the EUREKA CAN
• measure the volume of water that was displaced.
• repeat and take an average then calculate density with equation d= m\v

Question 3

how do you calculate the density of a regular object

Answer 3

• find the mass of the object
• use a ruler or vernier callipers to measure the width, height and length of the object and find out the volume
• do repeats and find an average
• use the equation to find out the density

Question 4

units of density (2)

Answer 4

g/cm cubed

kg/m cubed

Question 5

the density of the object depends on

Answer 5

what its made of, not its size

Question 6

the density of an object determines if the object will

Answer 6

sink or float

Question 7

a solid object will float on a fluid if it has a _____ density than the fluid

Answer 7

lower

Question 8

a solid object will sink if it has a _____ than the fluid

Answer 8
