Category 1: Properties & Matter
Anything that has mass and takes up space.
What is Matter?
The basic unit from which all matter is made
What is an Atom?
The amount of matter in an object
What is Mass?
What is the formula used to measure density?
What is Density = Mass / Volume?
A change in the form or appearance of matter that does not turn any substance into a different substance
What is a Physical Change?
A characteristic that can be observed without changing the matter into another type of matter.
What is a Physical Property?
Substances that are made of only one type of atom
What is an element?
The amount of space that matter occupies
What is Volume?
What is the density of an object whose mass is 180 grams and volume is 45 mL?
What is 4 g/mL?
A change in matter that produces one or more new substances
What is a Chemical Change?
A characteristic that describes something’s ability to become something else
What is a Chemical Property?
A group of two or more atoms held together by chemical bonds
What is a Molecule?
A measure of the force of gravity on an object
What is Weight?
What is the formula used to find Mass when given density and volume?
What is Mass = Density x Volume?
Which of the following is a physical change: a marshmallow burning, milk turning sour, or icicles melting?
What is Icicles Melting?
A single kind of matter that always has a specific makeup, or composition
What is a Substance?
A substance made of two or more elements that are chemically combined in a set ratio
What is a Compound?
This is a measure of the mass of a material in a given volume
What is Density?
What type of separation method is used by an air purifier to remove dust and allergens from the air?
What is Filtration?
Which of the following shows a chemical change: water boiling, silver coins melting, or two clear liquids producing yellow chunks?
What is two clear liquids producing yellow chunks?
The ability to dissolve in water and conduct electricity are examples of these types of properties
What are Physical Properties?
Made up of two or more substances that are together in the same place, but their atoms are not chemically bonded
What is a mixture?
Why is mass a better unit for measuring matter than weight?
What is because mass does not change with gravity?
If an object has a density of 2 g/cm³ and a volume of 10 cm³, what is its mass?
What is 20 grams?
This law states that matter is neither created nor destroyed during chemical or physical changes
What is the Law of Conservation of Matter?
