Principles
How do scientists define matter?
Anything that has mass and volume
The "Stuff" that makes the universe
What is the basic SI unit of mass?
Kilogram (kg) or Gram (g)
Chemical property of Matter that allows a substance to burn.
Flammability
A specific type of atom.
an element
How does a physical change differ from a chemical change?
In a physical change the substance is unchanged.
What is mass?
The amount of matter in an object
What does cm3 measure?
Volume
The amount of something in a space is a way to think about this physical property
density
Two or more elements chemically bonded together.
compounds
These mixtures look the same throughout
Homogeneous mixtures
What does volume measure?
The amount of space that an object takes up
What does mL measure?
Volume
A property of matter that can only be observed when that matter changes to a new type of matter.
What is a chemical property?
A combination of two or more substances without a defined ratio
Mixtures
These mixtures look uneven
heterogeneous
What is density?
The amount of mass per unit volume
What does g/mL measure?
Density
Odor is an example of this
Physical property of Matter or a sign of a chemical change if it's a new odor
Why can an element be identified by its properties?
Each element has unique physical and chemical properties.
compound
The curve at a liquids surface
meniscus
Why were we able to have 49mL of water with a mass of 49g?
Water has a density of 1g/mL
Ability of matter to combine chemically with other substances. Rusting or oxidizing for example
Reactivity
pure water is a
