1. UNIDAD: 3.- LA MATERIA DEL UNIVERSO
LA MATERIA Y SUS PROPIEDADES:
• Los materiales que forman el universo: Todo el universo conocido está formado por los
mismos materiales. Los materiales que forman la Tierra son los mismos que los que forman la Luna, Júpiter
o el Sol.
• Materia: Es todo aquello que tiene masa y volumen.
• Sustancia: Es cada uno de los distintos tipos de materia.
• Propiedades de la materia:
- Propiedades generales: Son las que tienen en común toda la materia y nos permite reconocerla.
Son propiedades generales:
- La masa: es la cantidad de materia que tiene un cuerpo
- El volumen: es el espacio que ocupa esa materia.
- Propiedades específicas: Son las que nos permiten diferenciar unos materiales de otros.
- Algunas propiedades específicas son: el color, el brillo, el tamaño, la forma, la dureza, la
densidad, la elasticidad, etc.
MEDIDA DE LA MATERIA:
• Magnitud: Es cualquier propiedad de la materia que se puede medir, por ejemplo: el peso, la
longitud, la velocidad, etc.
• Medir: Es comparar una magnitud con la unidad, por ejemplo: 3 kg., 2 m., 50 km/h, etc.
• Sistema Internacional de Unidades (S.I.): Casi todos los países del mundo han adoptado
este sistema de unidades, de manera que casi todo el mundo medimos de igual forma.
En la siguiente tabla podemos ver las unidades más importantes:

Longitud Metro m Cinta métrica
Masa Kilogramo Kg Balanza
Tiempo Segundo s Reloj
Temperatura Grados Kelvin ºK termómetro
LA DENSIDAD:
• Densidad: Es la relación que hay entre la masa de un cuerpo y el volumen que ocupa.
Matemáticamente se expresa así:
m masa
d= (densidad = )
v volumen
La unidad más importante para medir la densidad es el g / cm3, también se usa el kg / m3.
• Masa: es la cantidad de materia que tiene un cuerpo. La masa no varía de un lugar a otro, un
cuerpo tiene la misma masa en la Tierra o el la Luna. Su unidad más importante es el kg.
• Peso: Es la fuerza con que la Tierra atrae un cuerpo. El peso varía de un lugar a otro, un
mismo cuerpo no tiene el mismo peso en la Tierra o en la Luna. Su unidad la estudiaremos más adelante.
• Volumen: Es el espacio que ocupa un cuerpo, es decir lo grande o lo pequeño que es, su
unidad más importante es el m3, aunque los cuerpos más pequeños se miden en cm3.
MATERIALES:
• Los objetos están fabricados con múltiples materiales. Cada material se selecciona
cuidadosamente en función de sus propiedades.
• La creciente industrialización exige que busquemos nuevos materiales para fabricar objetos
novedosos o mejorar los antiguos materiales.
• Nuestro conocimiento científico también nos permite fabricar sustancias que nunca han
existido. Por ejemplo recientemente se han inventado: medicamentos, insecticidas, plásticos, barnices,
pinturas, fibras, etc.

UNIT: 2.- THE MATTER OF THE UNIVERSE
THE MATTER AND THEIR PROPERTIES:
• The materials that form the universe: The whole known universe is formed by the
same materials. The materials that form the Earth are the same ones that form the Moon, Jupiter or
the Sun.
• Matter: It is everything that has mass and volume.
• Substance: It is each one of the different matter types.
• Properties of matter:
- General properties: They are those that all matter shares and allows us to recognize matter.
These are general properties:
- Mass: it is the quantity of matter that a body has.
- Volume: it is the space that occupies this matter.
- Specific properties: They are those that allow us to differentiate some materials from others.
- Some specific properties are: the colour, the shine, the size, the form, the hardness, the
density, the elasticity, etc.

MEASURE OF MATTER:
• Magnitude: It is any property of matter that you can measure, for example: the
weight, the length, the speed, etc.
• To measure: It is to compare a magnitude with the unit, for example: 3 kg., 2 m., 50
km/h, etc.
• International System of Units (S.I.): Almost all the countries of the world have
adopted this system of units, so that almost everybody measures in the same way.

THE DENSITY:
• Density: It is the relationship between the mass of a body and the volume that it
occupies.
Mathematically it is expressed this way.
m mass
d = ( density = )
v volume
The most important unit to measure the density is the g / cm3, it is also used kg / m3.
• Mass: it is the quantity of matter that a body has. The mass doesn't vary from one
place to another; a body has the same mass on the Earth or the Moon. The most important unit is
the kg.
• Weight: It is the force with which the Earth attracts a body. The weight varies from
one place to another; one body doesn't have the same weight on the Earth or on the Moon. We will
study the units later.
• Volume: It is the space that a body occupies, or how big or small that it is, the most
important unit is the m3, although the smallest bodies are measured in cm3.
