,A measurement of the gravitational force acting on an object. -
Answer: Weight
Changes matter undergoes without changing composition. -
Answer: Physical changes
Properties of matter that can be observed or measured without
trying to change the composition of the matter being studied. -
Answer: Physical properties
Changes matter undergoes that involve changes in composition. -
Answer: Chemical changes

, A way of representing numbers consisting of a product between a
nonexponential number and raised to a whole-number exponent
that may be positive or negative. - Answer: Scientific notation
The numbers in a measurement that represent the certainty of
the measurement, plus one number representing an estimate. -
Answer: Significant figures
The number given when the mass of a sample of a substance is
divided by the volume of the same sample. - Answer: Density
The relative mass of a molecule expressed in atomic mass units
and calculated by adding together the atomic weights of the
atoms in the molecule. - Answer: Molecular weight
a stable subatomic particle occurring in all atomic nuclei, with a
positive electric charge equal in magnitude to that of an electron,
but of opposite sign. - Answer: Protons
a subatomic particle of about the same mass as a proton but
without an electric charge, present in all atomic nuclei except
