1.1 Matter
This has mass and takes up space
Matter
Substances in a ________________ retain their own properties
Mixture
shows the elements in the compound and the ratio of atoms.
Chemical formula
the amount of matter in an object. Mass is a physical property.
Mass
the amount of space that matter occupies.
Volume
a single kind of matter that has a specific composition
What is a substance
Honey is an example of what kind of a mixture as its substance is very evenly distributed.
Homogenous
When liquids can be separated from each other by heating them up to the temperature at which one boils into a gas leaving the other intact this process is called
Distillation
the measurement system used by scientists to measure the properties of matter.
International System of Units
length x width x height (lxWxH)
l x w x h
Solid Liquid and gas are
Three primary states of matter
True or false. Atoms in a mixture are chemically bonded.
False
When solids can be separated by pouring the mixture through a filter.
Filtration
The SI Unit of mass
the Kilogram or KG. Smaller units are grams (G).
a measure of the mass of material in a given volume.
Density
The simplest type of a substance is an
element
a substance made of two or more elements in a set ratio.
Compound
There are how many known elements
118
The SI Unit of Volume
cubic meter (m3), cubic centimeter (cm3), Liter (L), and milliliter (mL)
kilogram per cubic meter (kg/m3)
The SI Unit of Density
When elements form compound their ______________ can change
Properties
What is an atom
the basic particle from which all elements are made.
says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion.
Kinetic Theory of Matter
States that matter is not created or destroyed in any chemical or physical change. Also called the law of the conservation of matter.
Law of the conservation of Mass
Formula For Density
Divide the Mass by the volume
