The particulate nature of matter
States of Matter
liquids
types of motion
Move around each other
distinguish properties
Has a definite volume and takes the shape of the container
particle arrangement
Close together, with no regular arrangement
gases
types of motion
Move in different directions
particle arrangement
Seperated, with no regular arrangement
distinguish properties
Has no definite shape or volume
solids
types of motion
Vibrate on the spot
particle arrangement
Arranged in a regular, fixed arrangement, held in place by chemical bonds
distinguish properties
Has a definite shape and volume
Change of State
Evaporation
The process of an element or compound transitions from its liquid state to its gas state below the temperature at which it boils
Freezing
A transition where a liquid turns into a solid when its temperature is lowered below its freezing point.
Boiling
The transition from the liquid state to the gas state, usually occurring when a liquid is heated to its boiling point.
Condensation
The change from the gas phase into the liquid phase, it is the slowing down of a gas molecules as they join together to create a liquid
Melting
The change from a solid to liquid, occurs when the molecules of a solid speed up so that the motion overcomes the attractions and the molecules can move past each other as a liquid.
Diffusion (movement of particles)
Molecule
a group of two or more atoms held together by chemical bonds.
Ion
a particle, atom or molecule with a net electrical charge
Atom
the smallest particle of a chemical element that can exist
dependence of rate of diffusion on molecular mass
Heavier molecules move more slowly, also higher temperatures increase the energy a the movement of the molecules increase the rate of diffusion
