The Particulate Nature Of Matter
Solid
Very closely packed in an orderly manner
Vibrate about their fixed positions
Particles are held together by very strong forced of attraction
Particles gain heat energy which is converted to kinetic energy. Vibrates vigoursly in fixed positions until it gains enough heat to overcome the strong forces of attraction and change into the Liquid State
Gas
Move randomly and quickly
Particles are held together by weak forces of attraction
Far apart and arranged in a disorderly manner
Liquid
Closely packed in a disorderly manner
Move randomly and slip and slide past one another
Particles are held together by strong forces of attraction
Particles gain heat energy which is converted to kinetic energy. Slip and slide over each other until it gains enough heat to overcome the strong forces of attraction and change into the Gaseous State
Expansion
When a substance in the solid state is heated, its
particles gain energy and vibrate more vigorously
about their fixed positions. The distances between the particles increases. This causes the
volume of the substance to increase
. As a result, the substance expands
Contraction
When a substances in the solid is cooled, its particles lose energy and vibrate less vigorously about their fixed positions. The distances between the particles decrease. This causes the volume of the substance to decrease. Thus the substance contracts
The number and size of the particles in a substance do not change during expansion and contraction. Thus there is conservation of mass
Mass does not change
Diffusion
Definition
:Net movement of particles from a region of higher concentration to region of lower concentration
