this is the number of which the metric system is based upon
what is 10
produces a new substance with new properties
what is a chemical change
a measurement that is close to a known or accepted value is considered
what is accurate
a substance made up of two or more elements that are chemically combined in a set ratio
what is a compound
anything that has mass and takes up space
what is matter
45g is ______ kg
what is .045kg
a change in state
what is a physical change
divide mass by volume to determine this quantity
what is density
weight takes this phenomena into account
what is gravity
the base unit used for measuring the volume of liquids
what are liters
the base unit for measuring mass
what are grams
a change in which energy is released
what is an exothermic change
a group of measurements that are close to each other is considered
what s precise
an approximation based on reasonable assumptions
what is an estimate
the curved level of a liquid in a graduated cylinder or container
what is a meniscus
the acronym used to remember metric prefixes
what is K H D B D C M
a change in which energy is absorbed
what is an endothermic change
the amount of space that matter occupies
what is volume
a mixture in which you can easily see and separate the different parts
what is a heterogeneous mixture
the study of matter and how matter changes
the base unit for measuring length
what are meters
changes in shape or form
what is a physical change
explain one way to obtain the volume of an irregular solid
fill a graduated cylinder, record initial volume, drop irregular solid in, record new volume, subtract final-initial
a mixture is different than a compound because
in a mixture, each substance keeps its own properties. in a compound, we see different properties than the original elements.
