States of Matter Flashcards
(25 cards)
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
freezing
The change of a state of matter from a liquid to a solid
vaporization
The change in state from a liquid to a gas
condensation
The change in state from a gas to a liquid
Charles’s Law
When the temperature of a gas at constant pressure is increased, its volume increases. When the temperature of a gas at a constant pressure is decreased, its volume decreases.
Inversely Proportional
When the product of two variables is constant and proportional to each other.
Directly Proportional
When a graph of two variables is a straight line passing through the origin, the variables.
Boyle’s Law
When the temperature of a gas at constant temperature is increased, its volume decreases. When the pressure of a gas at a constant pressure is decreased, its volume increases.
Small Particle Theory - (SPT)
Liquids - Definite volume no definite shape
/Less tightly packed together than solids and more than gas; Flows freely, fluid, random
///Solids - Definite volume and definite shape/Very, very tightly packed sometimes arranged in a perfectly repeating geometric pattern
///Gas - No definite volume or shape.
/Random, high energy moves fast and collides with each other
Formula for BOYLE’S Law -
> P = <V and <P = >V
P=pressure
V=volume
Graph would be inversely proportional
