Properties of Matter
Anything that has mass and takes up space.
What is matter?
Matter is made up of this.
What are particles?
Cutting a piece of paper is an example of this.
What is a physical change?
When two or more different substances are mixed, a new substance may be formed.
What is a chemical change?
This is the scientific study of what matter is made of and how it changes?
What is chemistry?
People can use this to describe and identify matter.
What are properties?
They are too small to be seen.
What is a characteristic of a particle?
During a physical change, the total ________ of matter is conserved.
What is weight or mass?
When a chemical change occurs, the total weight of matter does what?
What is stay the same/is conserved/ or no matter is gained or lost?
Matter is made up of particles too small to be seen. These are called?
What are atoms?
This is the ability for a substance to dissolve.
What is solubility?
Air is this.
What is an example of a particle that makes up matter?
What is an example of a chemical change?
cooking or baking, change in odor, change in temperature, etc.
Matter made up of a single type of atom is called this.
What is an element?
What are properties?
Blowing up a balloon can be used as a ___________ to show that particles exist.
What is a model?
In your own words, describe a physical change.
cutting a paper, ice melting
Formation of gas, change in color, change in odor, change in temperature, emission of light, and the formation of a precipitate are examples of this.
What is a chemical change?
All of the atoms of an element are this.
What is identical?
Give an example of evidence that can be used to explain that matter is made of particles too small to be seen.
inflating a balloon, evaporating liquids, dissolving a substance
How can you prove that the total weight of matter is conserved during a physical change?
measure the matter before and after the change.
What kind of evidence of a chemical change would you expect to find when you burn a match?
What is change of temperature or emission of light.
Describe a molecule.
Molecules are formed when atoms join together with other atoms.
