Density and Graphing




What is Density
Density is Mass divided by volume. It is a measurement of the amount of matter in a given volume of something. Density is a very important property which can be used to identify a substance. Density is usually expressed in Kg/L, Kg/m3or g/cm3

Graphing
All graphs must contain 5 important things
1.) Labelled axis
2.) Appropriate scale
3.) Title
4.) Data points
5.) Line of best fit

Three things can be done when working with graphs
1.) Be able to read the graph
2.) Be able to find the slope
3.) Be able to find the area under the graph
