Teas 7 Chemistry
Solid to Liquid -
Melting (absorbs energy)
Liquid to Solid -
Freezing, (releases energy)
Liquid to Gas -
vaporization/absorbs energy
Gast to Liquid -
condensation/ release energy
Gas to Solid -
deposition/ release energy
Solid to Gas -
sublimation
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? -
Liquid
Which state of matter has atoms that vibrate in place? -
Solid
Solute -
A substance that is dissolved in a solution.
Solvent -
the substance in which the solute dissolves
Solution -
A homogeneous mixture of two or more substances
Osmosis -
Diffusion of water through a selectively permeable membrane
Diffusion -
Movement of molecules from an area of higher concentration to an area of lower
concentration.
Osmosis -
