CHEMISTRY: THE MOLECULAR NATURE OF
MATTER AND CHANGE ACTUAL TEST PAPER
QUESTIONS AND SOLUTIONS GRADED A+
◉ matter
Answer: anything that has mass and occupies space
◉ solid
Answer: A form of matter that has a definite shape and volume
◉ liquid
Answer: A state of matter that has no definite shape but has a
definite volume.
◉ gaseous
Answer: having the form of gas; also, lacking substance or solidity
◉ plasma matter
Answer: Liquid matter being heated higher = plasma matter. *The
most common type of matter*, plasma matter contains particles that
vibrate so fast that they shoot off the atoms. The atoms, w/o their
electrons, become ions
,◉ Bose-Einstein Condensate
Answer: new state supposedly formed when absolute zero is
reached or very nearly reached
◉ What happens to the water molecules when heat is added?
Answer: When heat is added, the water molecules start moving
faster. After a minute or so, the molecules are far apart from each
other and bouncing around the container.
◉ What happens to the water molecules when heat is removed?
Answer: When heat is removed, water molecules start moving closer
to each other. After a minute or so, the molecules start to form
connected rings, sitting on the bottom of the container, simply
vibrating, but not bouncing or sliding over each other.
◉ What is the arrangement of water molecules in the gaseous,
liquid, and solid states?
Answer: In the liquid state, the molecules are mostly sitting near the
bottom of the container and bumping around in a group, but moving
freely. They are actually packed closer together in the liquid phase
than when they are in the solid phase (and forming connected
"rings").
◉ solid
,Answer: are connected tightly to each other, often in a very ordered
way.
◉ solid
Answer: These particles may be atoms, ions, or molecules.
◉ liquid
Answer: in close contact with each other, but they're not tightly
bound together; they can move freely
◉ liquid
Answer: take shape of the container
◉ gas
Answer: often collide with each other, but they're unbound and free
to move in space between collisions.
◉ gas
Answer: take up the shape and volume of the container in which
they are kept.
◉ gas
Answer: A state of matter with no definite shape or volume
, ◉ plasma
Answer: When a gas is superheated, it forms an electrically charged
cloud called
◉ plasma state
Answer: The matter in the sun and most other stars is in the
◉ Bose-Einstein Condensate
Answer: happens under super-cold conditions. In this state, the
particles of matter look like small, fuzzy balls. This state was first
predicted in 1925 by Satyendra Nath Bose and Albert Einstein,
which is where it got its name.
◉ solid
Answer: because these particles are tightly connected, they can only
move my vibrating in place.
◉ solid
Answer: don't compress or expand easily
◉ solid
Answer: tight connection mans means closely packed
