Material objects have in common mass and volume.
why we say that mass and volume are general properties of matter.
SPECIFIC PROPERTIES OF MATTER.
The different materials are distinguished by their specific properties.
Some of these properties are heat, shape, taste, hardness, elasticity and transparency.
THE THREE STATES OF WATER.
You know that in nature you can find water in three different states: solid, liquid and gas. This is because their melting and boiling points are within the temperature range land.
SOLID.
- have their own way.
- Son incomprehensible, do not change their volume when pressed
- Increases in volume with temperature.
LIQUIDS.
- They have their own way. They adapt to the shape of their container and its free surface is horizontal when in equilibrium.
- remain virtually unchanged in volume to compress.
- its volume increases with temperature.
vaporization and condensation.
The transition from liquid to gas is called vaporization occurs at any temperature in the liquid surface. The reverse change is called condensation.
SUBLIMATION AND CONDENSATION.
The direct passage from solid to gas is called sublimation.
is the association of air fresheners solids or mothballs products.
The reverse change is called condensation.
melting and solidification.
The transition from solid to liquid is called melting and occurs at a temperature called the melting point. The reverse change is called solidification.
TYPES OF MIXTURES.
mixtures consist of more than one component, whose proportions may vary. These components do not lose their properties characteristics because of mixing.
· · Mix heterogeneous: is when its components can be distinguished with the naked eye.
· · Mix homogeneous: is when it appears uniform, and there are no distinct parts.
° ° solutions: are homogeneous mixtures are formed by the solvent and solute .
