Chapter 3 Flashcards
all_____ is made up of atoms and molecules
Particles are always in motion
the particles are extremely small
Matter
state of matter in which atom and molecules are tightly packed together
-Definite shape and volume
-crystalline
-amorphous
Solid
made of particles arranged in a regular repeating pattern
Crystalline solids
made of particles with no specific arrangement
Amorphous solids
state of matter in which atoms and molecules are close together but can slide past each other. More energy than solids.
-No definite shape
-definite volume
Viscosity
Liquids
of liquids is a property that is affected by the strength of the attraction between the molecules.
-It is the resistance of a liquid or gas to flow.
- High _______- substance flows slowly; low ________- substance flows faster.
Viscosity
State of matter i which atoms or molecules move freely and spread apart. More energy that solids and liquids
-no definite shape or volume
-Boyle’s Law
-Charles Law
Gases
the relationship between volume and pressure for a fixed amount of gas. EX. Weather balloon-as air pressure decreases the volume of the balloon increases
Boyle’s Gas Law
the relationship between temperature and volume for a fixed amount of gas. EX. Heating a balloon will cause the volume of the balloon to expand.
Charles’s Gas Law
can be determined by measuring the speed of molecules
Temperature
is measured in three dimensions length x width x height
Volume
the amount of force applies per unit of a surface. It increases when the amount of force per unit area increases.
Pressure
the force the acts on the surface of a liquid that minimizes the area of the surface. Ex. Vinegar has lower _________ than vegetable oil
Surface Tensions
the physical forms of matter that include solids. liquids and gases. Ex. ice, water, steam
States of matter
the change of a substance from one physical state to another. Ex. Liquid soup boils & turns to steam
Melting
Freezing
Evaporation
Condensation
Sublimation
Changes of states
