Activate 1 - Chapter C1 - Particles Flashcards
States of Matter
The States of Matter is a solid melting into a liquid, the liquid evaporates into a gas, the gas is condensing into a liquid, the liquid freezes into a solid and then all over again.
Solid Particles
Solid particles are strongly attached to each other. The particles are touching. The particles are in a regular arrangement. The particles can’t move position but they vibrate.
Liquid Particles
The particles are quite strongly attracted to each other. 2/3 of the particles are touching. The particles aren’t in a regular arrangement. The particles can slide past each other.
Gas Particles
The particles are far apart. The particles have a lot of kinetic energy and move rapidly. The attraction of the particles is very weak. The particles aren’t in a regular arrangement.
Melting
The change of state for solid to liquid.
Change of State
The process by which a substance changes from one state to another.
Freezing
The change of state from liquid to solid.
Melting Point
The temperature which a substance melts.
Evaporation
The change of state from liquid to gas that occurs when particles leave the surface of the liquid only. It can happen at any temperature.
Condensation
The change of state from gas to liquid.
Sublimation
The change of state from solid to gas.
Diffusion
The movement of liquid or gas particles from a place of high concentration to a place of low concentration.
Material
The different types of stuff that things are made from.
Particles
The tiny things that materials are made from.
Mixture
A material whose properties are not the same all the way through.
