States of Matter Flashcards
What is a Fluid?
A fluid is a free flowing liquid aka (another word for liquid).
What is a solid?
A solid is the state of matter that has a definite shape and definite volume.
Define Crystalline Solid
A Crystalline solid is a solid that is made up of crystal patterns.
Surface Tension
An inward force or pull amongst the molecules in a liquid that brings the molecules on the surface closer together
Amorphous Solid
Particles not arranged in regular pattern, does not melt at a distinct temperature
Liquid
Has a definite volume but an indefinite shape
Viscosity
A liquid’s resistance to flowing, depends on size and shape of it particles and attractions between the particles
Gas
No definite shape or volume
Pressure
Is the force of its outward push divided by the area of the walls of the container
melting
The change in a state from a solid to a liquid
Melting point
When melting occurs at a specific temperature
evaporation
Takes place only on the surface of a liquid
sublimation
Occurs when the surface particles of a solid gain enough energy that they form a gas
boiling
Takes place both below and at the surface of a liquid
boiling point
The temperature of which a liquid boils
