Intro to Matter #1
Anything that has mass and takes up space.
What is matter?
The amount of space an object takes up.
What is volume?
A property that can be observed or measured without changing the identity of the substance.
What is a physical property?
These are the single particles that make up all matter.
What are atoms?
Oxygen, copper, and potassium are all examples of this.
What are elements?
The measure of the amount of matter in an object.
What is mass?
The volume of this shape is equal to its length times its width times its height.
What is a rectangle?
A property that describe's a substances ability to form new substances.
What is chemical property?
A substance that is made up of more than one kind of atom.
What is a compound?
A change in which one or more substances change into entirely new substances.
What is a physical change?
The gravitational pull on an object.
What is weight?
This device is used to measure an object's weight.
What is a scale?
Boiling point and electrical conductivity are examples of these.
What are physical properties?
This term describes substances that cannot be separated into their component parts through physical changes.
What are pure substances?
This results when one substance dissolves in another.
What is a solution?
This is used to measure an object's mass.
What is a balance?
The measure of the amount of mass in a given volume.
What is density?
To observe this property, you must attempt to change the identity of the substance.
What is a chemical property?
Mixtures that are the same throughout.
What are homogeneous mixtures?
This states that mass cannot be created or destroyed in ordinary chemical and physical changes.
What is the law of conservation of mass?
A 300 gram object with a volume of 10 ml has this density.
What is 3 g/ml?
The volume of water displaced by an object is equal to this.
Flammability is an example of this.
What is a chemical property?
A heterogenous mixture in which some particles settle out due to gravity.
Changing color or odor, heat production, fizzing and foaming, and giving off sound or light are all signs of this.
What is a chemical change?
