Matter
Anything that takes up space
Mass
the amount of matter in an object
How Does Matter Change?
Matter usually changes state when you add or take away heat, which changes the temperature
of the matter
Substance
A single kind of matter that is pure and has a specific set of properties.
examples of substances
1. Water
2. Alcohol
, 3. Oil
4. Food coloring
Solids
The particles in solids are tightly packed
Liquids
Liquids are also a condensed phase, however, in contrast to solids, the particles have some
translational kinetic energy, which means they have freedom to move
gas phase
the phase of matter in which atoms or molecules can move essentially independently of one
another
Which state(s) of matter take the shape of their container?
Liquids and gases take the shape of their containers since, they do not have definite shape and
volume. Only solids have definite shape and volume.
SOLIDS
have the least volume
LIQUIDS
have a definite volume
GASES
have maximum volume
Which of the following is correct?
(a) Solids have a definite shape and definite volume.
(b) Liquids have a definite volume but no definite shape.
(c) Gases have a definite volume but no definite shape.
(d) Liquids have both definite shape and definite volume.
(a) Solids have definite shape and definite volume.
(b) Liquids have definite volume but no definite shape.
Which state of matter has atoms that move freely?
Gas
Which state of matter has atoms that can slide past each other?
