Iron, copper and stone are examples of raw materials whose origin is
-
Animal
-
Vegetable
-
Mineral
-
The final stage of the technological process is
-
The raw material
-
The processed material
-
The manufactured good
-
Clothes are made from
-
Textile
-
Wood
-
Metal
-
Stone
-
Ceramics
-
Plastic
-
With ceramics, I can make
-
A brick
-
A jacket
-
A plastic bag
-
A pencil
-
A material that can be easily shaped into filaments is
-
Malleable
-
Tough
-
Ductile
-
Plastic
-
When It breaks easily it is
-
Brittle
-
Elastic
-
Tough
-
Hard
-
A material that is not easily scratched by other materials is
-

When light passes through it, but we can not see any clear image, the material is
-
Traslucent
-
Impermeable
-
Trasparent
-
Conductor
-
If the material doesn't allow liquids to go through it, it is:
-
Permeable
-
Impermeable
-

-
Magnetic
-
The material that has good magnetic properties is
-
Carbon
-

-
Density can be calculated as
-
Mass over volumen
-
Volumen over mass
-
Mass times volumen
-
Mass plus volumen
-
If we compare the density of water and oil:
-
Water is denser than oil
-
Oil is denser than water
-
Both substances have the same density
-
Density is a property of solid objects
