Anything that has mass and takes up space is known as what?
What is matter made up of?
smaller particles (atoms)
Cutting a piece of paper is an example of change.
physical
When two or more different substances are mixed, a new substance may be formed. This is called a change.
Chemical
The scientific study of what matter is made of and how it changes is known as what?
Chemistry
People can us to describe and identify matter.
properties
What is a characteristic of particles?
They are too small to be seen
During physical change, the total of matter is conserved.
weight or mass
When a chemical change occurs, the total weight of matter does what?
Stays the same/is conserved/no matter is gained or lost
Matter is made up of particles too small to be seen. These are called what?
atoms
Describe solubility.
The ability of a substance to dissolve
What is an example of a particle that makes up matter?
air
What are the three states of matter?
liquid, solid, and gas
What is an example of a chemical change?
cooking, rusting, burning paper, rotting banana
Matter made up of a single type of atom is called a what?
element
Name three properties of matter
color, hardness, reflectivity, electrical conductivity, thermal conductivity, magnetism, and solubility
Blowing up a balloon can be used as a to show that particles exist
model
In your own words, describe a physical change.
A type of matter can change physically while remaining the same type of matter.
How do you know when a chemical change has occurred?
formation of gas, change in color, change in odor (smell), change in temperature, emission of light, and formation of a precipitate
All of the atoms of an element are what?
identical
Observations and measurable data of physical properties of matter can be used as evidence to describe types of matter.
What is an example of evidence that can be used to explain that matter is made of particles too small to be seen?
blowing up a balloon, evaporating a liquid, or dissolving a substance
How can you proves that the total weight of matter is conserved during a physical change?
measure the matter before and after the change occurs
What kind of evidence of a chemical change would you expect to find when you burn a match?
change in temperature or emission of light
Describe a molecule.
Molecules form when atoms join together with other atoms.
