1
Anything that has mass and takes up space
Matter
A 1 or 2 letter set used to identify an element (O=Oxygen)
Symbol
The measurement of how much matter an object contains
Mass
A combination of 2 or more atoms bonded together (O2)
Molecule
How could someone tell the difference between fool's gold and real gold?
Find the density, real gold is about 4x more dense
The study of the properties of matter and how matter changes
Chemistry
Mixture
What scientists use to measure the properties of matter (speaking the same language)
SI Units/International System of Units
What can you infer about the density of an object that floats on water?
The object is less dense that water
What is the equation for volume?
Length x Width x Height
A substance that cannot be broken down into other substances (building blocks of matter)
Element
When the appearance of a material changes, but the material itself stays the same (ripped paper)
Physical Change
The amount of space something takes up
Volume
True or False: Each specific substance has its own set of properties
True
What is the formula to calculate density
Density= Mass/Volume
Compound
A change in matter that produces a new substance (burnt paper)
Chemical Change
Measurement of how much mass in contained in a given volume (Mass/Volume)
Density
True or False: If you move an object away from the Earth, its mass will change
False. It's weight will change, not it's mass
What is the SI unit for mass
Kilogram
A combination of symbols that shows the ratio of elements in a compound (H20)
Formula
A measure of the force of gravity on you
Weight
The force that holds 2 atoms together
Chemical Bond
What are the smallest particles of an element?
Atoms
How are compounds different from elements?
Compounds are made up of elements
