Unit 1 - Simple Particle Describing Matter

Sapphire - This beautiful gemstone is an example of matter. Matter is composed of tiny indivisible spheres which have mass and occupy space

 

 

Matter is composed of featureless spheres which have mass and volume

Mass is a measure of how much stuff the object is made of.
Matter is conserved during all kinds of change because we are just rearranging the spheres.
Volume is a measure of how much space the object occupies.
These are properties of an object.
Density describes how much stuff for each unit volume.
This is a property of a substance.
