What are the 3 phases of matter
Solid, liquid, gas
Which types of matter has a fixed volume and mass
Solid and liquid
What are the 3 parts of an atom and what type of charge do they have.
Which 2 make up the nucleus
proton- positive
neutron- no charge or neutral
electron- negative
Protons and neutrons
what is a physical change
Form or shape of a substance changes but the substance has the same chemical makeup. Example- Ice to liquid to gas.
Not all ______________ are ______________,
but all ________________ are _____________
mixtures, solutions
solutions, mixtures
What is volume?
The amount of space occupied by matter
Which type of matter flows easily
Gas and liquid
What are the smallest parts of matter called
Atoms
What is nanotechnology
is the study of materials at the molecular (atomic scale). Nanoscale means one billionth of a meter! Example- Sunscreen
What type of reaction occurs for a mixture to be classified as a solution
Chemical
What is mass
Mass is commonly measured by how much something weighs
Which types of matter can be compressed
Liquid, a little , and a gas
What is an element
Type of matter made up of 1 type of atom
Give 3 example of elements
H- Hydrogen
O= Oxygen
C= Carbon
T or F
In a solution, 2 or more pieces of matter mix or combine together to create a totally new substance
True
What is density
Density = the mass of matter divided by how much space(volume) it occupies
D=M/V
This type of matter does not have a fixed volume, or shape
Gas
What is a the difference between a molecule and a compound
Molecule is made up of 2 or more atoms
Compound is made of of 2 or more different elements
give 3 examples of compounds
CO2- Carbon Dioxide
H2O- Water
NaCl- Sodium Chloride-Table Salt
NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3 . = Baking Soda
2000 LBS, 1 ton, of different rocks are pulverized by a machine and thrown into a pit. Is this a mixture or a solution
Mixture because you can always separate the different pieces. There is not a chemical reaction
What is a property
a characteristic or trait that you can use to describe matter by observation, measurement, or combination.
Which type of matter takes the shape of its container
Liquid and gas
The properties of a compound are often _________
than the elements that created it
Different
What is a chemical change and give an example
occur when atoms combine and create a new substance-
Water= H20
Give two examples of a mixture and 2 examples of a solution.
Solution- Salt water, Kool-Aid
Mixture- A bunch of nuts like the kids in this class, Cereal and milk
