Density

Question 1

Define density

Answer 1

Amount of matter in a given volume of space

Question 2

What is the formula for density?

Answer 2

Density = Mass / Volume

Question 3

What is the unit for density?

Answer 3

kg/m3 or g/cm3

Question 4

How does one figure out the density of a liquid?

Answer 4

Find the mass of the measuring cylinder.
Measure the mass of the cylinder with the liquid in.
The difference in values is the mass of the liquid.
Measure the volume of the liquid using the measuring cylinder.(1ml = 1cm3)
Use formula Density = mass / volume

Question 5

How does one figure out the density of a regular solid? e.g. a cube

Answer 5

Calculate the volume using volume formula(length x breadth x height)
Measure the mass with a scale
Use density formula

Question 6

How does one figure out the density of a irregular solid? e.g. a rock

Answer 6

Use a measuring cylinder full of water. 
Place object in measuring cylinder. 
Water will rise.
Difference in original water height and height with the object in it is the object's volume
Use density formula
