Solids, Liquids, & Gases Chapter 3

3.1 States of Matter SOLIDS -have definite shape and volume -fixed, closely packed arrangement of particles -crystalline solid- regular repeating pattern, melts at specific temperature -amorphous solid- not arranged in pattern, does not have a distinct melting temperature

Solids A fixed, closely packed arrangement of particles causes a solid to have a definite shape and volume.

Solids Solids that are made up of crystals are called crystalline solids. In amorphous solids, the particles are not arranged in a regular pattern.

LIQUIDS -has definite volume, but no definite shape -closely packed particles that are free to move -surface tension- attraction of molecules -viscosity- depends on the size and shape of its particles and the attraction between them high viscosity- flows slower (oil) low viscosity- flows quicker (water)

Liquids Because its particles are free to move, a liquid has no definite shape. However, it does have a definite volume.

Gases -flows easily and changes volume easily -particles move quicker than a solid or liquid -gas particles spread apart, filling all available space -has no definite volume or shape

Gases As they move, gas particles spread apart, filling all the space available. Thus, a gas has neither definite shape nor definite volume.
