Understanding States of Matter and Separation Techniques

States of Matter

DIBUJO: 1 Liquid 2 Boiling point 3 Evaporating 4 Sublimation 5 Condensation 6 Melting 7 Solidification 8 Reverse sublimation

Evaporating

: It's not necessary to vaporize at 100°C

Boiling

: It's when a substance transforms to the gas state at a temperature of 100°C or higher

Graph

: 1-First, it's a solid substance 2 then the temperature increases 3 the solid substance melts and starts being a liquid substance 4 the temperature increases 5 the liquid substance vaporizes and starts being a gaseous substance 6 the temperature increases

Verify Pure Substance

: We know that a substance is pure because it has specific properties.

Sand+water

: Sedimentation - the sand stays at the bottom of the container and the water can be separated from it. The sand is at the bottom

Oil+water

: Decantation - we use an object to separate both substances. The two substances are in the same container, so when the first substance has finished separating, you stop the process

Colloids

:

Aerosols

: They are gaseous substances, but there are dispersed solid and liquid particles

Gels

: They are solid substances that have dispersed small liquid particles

Sols

: They are liquid substances that have dispersed solid particles
