chem 134 exam 1 chapters 1-3-Questions with
Correct solutions
solid
Definite shape and volume
Crystaline solid
A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern
amorphous solid
lacks an ordered internal structure
liquid
A state of matter that has no definite shape but has a definite volume. - packed closely and able
to move
gas
a form of matter that does not have a definite volume or shape - freely move
heat:
solid ---> liquid ---> gas
cold:
gas ---> liquid ---> solid
pure substances:
element and compound
, element
A pure substance made of only one kind of atom
- cant be broken down
- building block of matter
- allotropes
compound
A substance made up of atoms of two or more different elements
- definite fixed proportions
- can be broken down
- chemically reactive
- combine with other elements to form compounds
mixtures:
homogenous and heterogenous
homogenous mixtures
mixtures that look the same throughout.
- atoms and molecules uniform
two types (solution and alloy)
solution
solvent + solute
alloy
