11.1 particulate Model of Matter
Particulate Model of Matter suggests that:
* All subject is made up of small discrete particles.
* The small discrete particles in matter are in constant random motion.
It is easier to explain the Particulate model of matter using models. A variety of objects toilet be used to represent the small discrete particles in matter.
11.2 Particulate Model for warms, liquiditys and Gases
A block of ice Solid molecules have a restricted motion = Solid
A beaker of boiling water system Gas molecules are able to bear at extremely high speed = Gas
A beaker of warm water liquid molecules have greater mobility = Liquid
States of Matter
Solid
* In solids, the molecules are lay close together in a regular pattern
* watertight attractive intermolecular forces hold the molecules in position so they have definite shape and volume
* They can only loom in their fixed positions
Liquid
* In liquids, the molecules are not place in a regular pattern and are slimly further apart then those in solids
* The attractive intermolecular forces are not very strong. Thus, the molecules are able to move among one another, giving liquids its definite volume but not a definite shape.
Gases
* In gases, the molecules are widely spaced. intermolecular forces are negligible
* The molecules move about randomly with high speeds, colliding with the walls of the container, occupying both available space.
Research on *phase deviates for water*
passion curve
(Please!!!!!! Research on the internet)
Freezing = variant change as a substance changes to Liquid to Solid
Melting = Phase change as a substance changes Solid to Liquid
Condensation = Phase change as a substance changes Gas to liquid
desiccation = Phase change as a substance changes Liquid to Gas
Important to note!!!!
* What the x and y axis means
* countersink words like melting, freezing,...If you want to get a near essay, order it on our website: Orderessay
