Teas 7 Chemistry Questions and
answers 2025/2026
Solid to Liquid correct answers Melting (absorbs energy)
Liquid to Solid correct answers Freezing, (releases energy)
Liquid to Gas correct answers vaporization/absorbs energy
Gast to Liquid correct answers condensation/ release energy
Gas to Solid correct answers deposition/ release energy
Solid to Gas correct answers sublimation
Matter correct answers Anything that takes up space
Mass correct answers the amount of matter in an object
How Does Matter Change? correct answers Matter usually changes state when you add
or take away heat, which changes the temperature of the matter
Substance correct answers A single kind of matter that is pure and has a specific set of
properties.
examples of substances correct answers 1. Water
2. Alcohol
3. Oil
4. Food coloring
Solids correct answers The particles in solids are tightly packed
Liquids correct answers 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 correct answers 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? correct answers 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 correct answers have the least volume
LIQUIDS correct answers have a definite volume
GASES correct answers 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. correct answers (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? correct answers Gas
Which state of matter has atoms that can slide past each other? correct answers Liquid
Which state of matter has atoms that vibrate in place? correct answers Solid
Solute correct answers A substance that is dissolved in a solution.
Solvent correct answers the substance in which the solute dissolves
Solution correct answers A homogeneous mixture of two or more substances
Osmosis correct answers Diffusion of water through a selectively permeable membrane
Diffusion correct answers Movement of molecules from an area of higher concentration
to an area of lower concentration.
Osmosis correct answers Diffusion of water through a selectively permeable membrane
Atom correct answers The smallest component and the most basic part of matter that
still retains its identity
Atomic structure correct answers Atoms have a nucleus and electrons. Its nucleus
contains protons and neutrons
Nucleus correct answers The part of the atom that houses the protons and the neutrons
Protons correct answers positively charged subatomic particles
Neutrons correct answers the particles of the nucleus that have no charge. they are
neutral and without a positive or negative electrical charge; the part of the atom that
gives the atom its isotope identity.
