an d an sw er s w ith accur ate
r ation ales(PASSED)
What is matter? - answer Anything that has mass and occupies space
What is mass? - answer A measurement of the amount of matter in an object
Does the mass of an object change by location? - answer No; it stays the same on
the moon, Earth, etc...
What is weight? - answer A measurement of the gravitational force acting on an
object
Does the weight of an object change by location? - answer Yes; it changes
depending on the location such as Earth vs. the moon
What are physical properties of matter? - answer Properties that can be observed
or measured without attempting to change the composition of the matter being
observed.
What are examples of physical properties of matter? - answer Color, shape, and
mass
, What are chemical properties of matter? - answer Properties that can be observed
or measured only by attempting to change the matter into new substances.
What are examples of chemical properties of matter? - answer Flammability and
the ability to react (e.g. when vinegar and baking soda are mixed)
What are physical changes of matter? - answer These changes take place without
a change in composition.
What are chemical changes of matter? - answer These changes are always
accompanied by a change in composition.
What are examples of physical changes of matter? - answer Examples: freezing,
melting, or evaporation of a substance
(e.g. water)
What are examples of chemical changes of matter? - answer Examples: burning of
paper and the fizzing of a mixture of vinegar and baking soda
What are atoms? - answer Tiny particles that all matter is made up of
What are elements? - answer Substances that are made up of atoms that are
identical
What are compounds? - answer Combinations of atoms of two or more elements.
