MATTER AND ITS PROPERTIES Flashcards
is made of particles that give its mass and volume
matter
5 phases of matter
- solid
- liquid
- gas
- bose-einstein condensate
- plasma
has its own shape and volume
solid
weakly attracted to one another, have fixed volumes, but take in shape of their container
liquid
weakest attraction, no fixed volume or shape
gas
a physical change where substance undergoes changes without changing its chemical composition
phase transitions
2 types of properties associated with matter
- physical property
- chemical property
properties that can be measured and observed without changing the material’s chemical composition
physical property
material’s possibility to undergo chemical change in its chemical composition
chemical property
Physical properties of matter can further be classified
- Intensive property
- Extensive property
substance specific properties that do not depend on the amount of the substance
intensive property
properties that do depend on the amount of substance
extensive property
components of matter that can be separated by physical means
mixture
cannot be broken down through physical means
pure substance
pure substance can be classified as an
element or compound
pure substance that can be broken down into simpler forms using chemical means
compound
pure substance that cannot be simplified
element
law that governs the combination of atoms to form compounds
law of constant composition or definite proportion
are forms of matter with no definite properties and are not combined chemically
mixture
mixture in which only one phase is visibly seen
homogeneous mixture
at least 2 different phases of matter or visible components
heterogenous mixture
indivisible particle
atom
Elements can be classified into 3
- Metals
- Nonmetals
- Metalloids
basic unit of an element
atom
good electrical conductors and heat conductors
metal
