everything that has mass, volume and density.
Properties of matter
● Time:
Amount of matter in an object
● Volume:
Space occupied by an object
● Density:
Relationship between mass and volume
Classification of matter
● Pure substances (elements and compounds)
● Mixtures (homogeneous and heterogeneous)
Importance of Matter
Matter is fundamental in our daily lives and in the universe in general
because:
● It constitutes everything that surrounds us: from the air we breathe to
the objects we use daily.
● It is essential for life: living beings are composed of organic matter.
● Basis of technology: Matter is used to create materials and devices that
improve our quality of life.
● Natural resources: matter is the source of resources such as minerals,
metals and fossil fuels
