TEAS-CHEMISTRY EXAM QUESTIONS
& VERIFIED CORRECT ANSWERS
objects that take up space and have mass. made up of elements. physical thermal
electrical and chemical properties (color, density,hardness,conductivity) - CORRECT
ANSWER matter
substances that cannot be broken down into simpler substances by chemical means. -
CORRECT ANSWER elements
everything in the physical world is make up of microscopic matter comprised of atoms or
molecules. - CORRECT ANSWER atoms&molecules
properties are the same throughout. coal and glass are examples - CORRECT
ANSWER homogenous matter
properties may vary in their make-up. concrete and soil are examples. - CORRECT
ANSWER heterogenous matter
the tiniest unit an element retains its characteristic properties. building blocks. they have
protons, neutron, and electrons. - CORRECT ANSWER atoms
core of an atom. protons and neutrons are particles that are packed together here. -
CORRECT ANSWER nucleus
positively charged - CORRECT ANSWER protrons
uncharged or neutral - CORRECT ANSWER neutrons
negatively charged particles that orbit outside of nucleus. in constant motion. small
compared to protons and neutrons. - CORRECT ANSWER electrons
the number of electrons is equal to the number of protrons: the charges inside and
outside the nucleus are balanced. - CORRECT ANSWER neutral atom
atoms have same number of protons but differ in number of neutrons in the nucleus. -
CORRECT ANSWER isotopes
when an atom loses or gain one or more electrons on the outside so the nucleus is not
equal to the number of protons on the inside. - CORRECT ANSWER ion
, atoms loses one or more electrons it becomes positively charged. - CORRECT
ANSWER cation
atoms gain one or more electrons it becomes negatively charged. - CORRECT
ANSWER anion
matter has neither definite shape nor definite volume - CORRECT ANSWER gas phase
matter has a definite volume but an indefinite shape. take the shape of heir containers. -
CORRECT ANSWER liquid phase
matter has both definite shape and definite volume - CORRECT ANSWER solid phase
condensed phases because the particles are very close together. - CORRECT
ANSWER liquids&solid
assume shape and volume of closed container.
particles separated with no regular arrangement no shape or volume
particles vibrate and rotate and they move freely at high speeds.
particles are compressible due to the distance between molecules.
flows easily because particles - CORRECT ANSWER properties of gas
takes shape of container
particles are close together with no regular arrangement have volume and shape
particles not easily compressible cuz there is little free space between particles.
particles flow easily because they can move or slide pat each other - CORRECT
ANSWER properties of liquid
retains volume and shape.
tightly packed in a pattern a rigid particles are locked into places have a geometric
pattern crystalline structure.
can vibrate but generally don't from place to place
not easily compressible there is little free space between particles.
does not flow because particles cant move or slide past each other. - CORRECT
ANSWER properties of solid
a form of energy - CORRECT ANSWER heat
measure the average kinetic energy of particles in a particular system. - CORRECT
ANSWER temperature
change in store or form. with a temperature change a substance will goo from a solid
phase to a liquid phase. if temperatures continue to raise it will go from a liquid phase to
a gas phase. - CORRECT ANSWER physical changes
