MATTER

PROPERTIES:

MASS: The weight of an object. We measure it in grames (g) with a scale.

VOLUME: The amount of space that an object ocupies. We measure it in cubic centimeters (cm2)
We meassure volume by the amount of water that has increased in a graduated tube

DENSITY: The amount of molecules in an object. We calculate density, dividing mass by volumen.

MATTER

 Everything arround us is made up of matter. It´s made up of small invisible particles called molecule or atom .

STATES: It can be solid, liquid or gas 
PROPERTIES: It can be mass, volume or density 
MASS: The weight of an object. We measure it in grames (g) with a scale (balanza)
VOLUME: The amount of space than an object ocupes. We measure it in cubic centimeters (cm3). The easiest way to measure volume is calculating the amount of water that has increased in a graduated tube (1 ml =1 cm3)
DENSITY: The amount of particles or molecules in an object . 
We calculate it >( d =mass/ volume =g/cm3)
