Fill the eureka can with water and place a measuring cylinder under the spout

Question 9

Whats the third step in the density required practical

Answer 9

Submerge the object in the water. Some will be displaced

Question 10

Whats the 4th step in the density required practical

Answer 10

Measure the volume of the displaced water. This is the volume of the object

Question 11

What makes a material more dense than another

Answer 11

If the particles are closer together

Question 12

What is the equation for density
