Properties and Definitions
This term means "matter that has a constant chemical composition and characteristics.
What is a substance?
Density is defined as this ratio (give the formula)
The temperature at which a solid becomes a liquid
What is melting point?
This term describes how well a substance dissolves in another substance
What is solubility?
The three most common states of matter on Earth
What are solid, liquid and gas
A characteristic of a substance such as shape, mass, or odor
What is a property?
If mass = 24.5 g and volume = 7 cm3, this is the density (give numeric answer with units)
The temperature at which a liquid becomes a gas
What is the boiling point?
Sugar dissolves in water but flour does not; sugar is called this in wate
What is soluble?
In this state particles are tightly packed, vibrate in place, and have fixed shape and volume.
What is a solid?
The amount of matter in an object
What is mass?
If two objects have the same volume, the object with this property will have more mass
What is higher density?
These two properties do not change based on how much of a substance you have.
The ability of a chemical to burn or ignite is called this
What is flammability?
In this state particles are close together but can slide past each other; the substance takes the shape of its container.
What is liquid?
This property does not change based on the amount you have and can be used to identify a substance
What is melting point, boiling point, or density?
Density is useful because it does not depend on this about an object (two-word answer)
What is shape or size or amount?
When thermal energy is added and particles move faster, matter often changes through these processes (name two).
A common lab test using a burning splint helps identify certain gases; name one gas that reacts explosively to a lit splint.
What is hydrogen?
In this state particles are spread far apart, move quickly, and have no fixed volume or shape
What is gas?
A mix of different substances like cellulose and lignin in wood or nitrogen and oxygen in air.
What is a mixture?
You have a silver necklace and a silver earring. Using this property (and the mass/volume ratio) allows you to determine whether both are the same substance.
What is density?
According to the notes, the temperature of a substance determines this
What is states of matter?
Permanent marker ink is not soluble in water but dissolves in liquids like these (name one).
What is isopropyl alcohol or mineral oil?
Explain how particle motion changes when matter goes from solid to liquid
What is: particles gain energy and move from vibrating in place to sliding past each other (increased motion)?
