100
A characteristic of a substance than can be observed and measure without changing the identity
What is physical property?
100
A change that affects one or more physical properties of a substance
What is physical change?
100
The smallest unit of an element
What is an atom?
100
A substance that has a definite volume and shape
What is a solid?
200
Lwh & D= m/v
What is the formula for finding density and volume?
200
Describes a substances ability to change into a new substance with different properties
What is chemical property?
200
A change that occurs when one or more substances change into entirely new substances with different properties
What is chemical change?
200
One or more of the same kind of atom chemically combined
What is an element?
200
The change in state from a gas directly to a solid
What is deposition?
300
You use a spring scale
How do you measure weight?
300
The ability of a substance to be rolled or pounded into various shapes
What is malleability?
300
The particles have more than average kinetic energy and it makes reactions happen faster
How does temperature affect chemical changes?
300
A substance that has a definite physical and chemical properties such as appearance, melting point, and reactivity
What is a pure substance?
300
It is frozen carbon dioxide
What is dry ice?
400
A measure of the amount of mass in a given volume
What is density?
400
Density, solubility, thermal conductivity, electrical conductivity, malleability, luster, melting point, boiling point, magnetic attraction
What are the common physical properties?
400
Production of a gas, production of an odor, formation of a precipitate, change in color, & change in energy
What are five signs that a chemical change has happened?
400
Metals on the left, nonmetals on the right, and metalloids in the middle
How is the periodic table of elements classified/organized?
400
They are close together but can still move together in one direction and have more kinetic energy than a solid
What are the particles in a liquid like?
500
A measure of the gravitational force on an object
What is weight?
500
The ability of a substance to dissolve in another substance
What is solubility?
500
