Properties of Matter
A characteristic of a substance that doesn't change
Property
The state of matter that has a definite shape and a definite volume
A physical setup that traps matter inside so it cannot enter or leave, but allows energy like heat or light to pass through
The smallest unit of a substance that still has all the properties of that substance.
Molecule
The act of carefully watching, noticing, or listening to something to gather information
Observation
The property that describes how tightly packed the mass is inside an object compared to the space it takes up
Density
The state of matter that has no definite shape but does have a definite volume.
Liquid
A physical setup that allows matter inside to enter or leave.
Open system
A process in which one or more substances are converted to one or more different substances.
Chemical Reaction
A physical, mathematical, or conceptual representation of a real-world system or object.
Model
The property that describes how a substance interacts with fire.
Flammability
The state of matter that has no definite shape or volume
Gas
In this type of system, the total mass stays the same because no matter can escape.
Closed system
The process where a solid breaks apart into particles too small to see and mixes completely in a liquid.
When you notice that salt disappears into water when stirred, you've made this type of scientific act.
Observation
The property that tells you whether a material can break apart and mix completely in a particular liquid
Solubility (soluble)
Any substance that has mass and occupies space, existing in states like solid, liquid, or gas
Matter
If you leave a cup of water uncovered and the water evaporates away, your setup was this kind of system
Open System
When you stir sugar into tea until you can't see it anymore, you've done this to the sugar
Dissovle/Dissolving (will also accept soluble)
A diagram of the water cycle is an example of this; it represents a real system but isn't the real thing.
Model
The property that tells you whether a material will NOT dissolve in something else
Insolubility (insoluble)
When ice melts into water, the water is in which state of matter?
Liquid
A sealed, insulated container that lets light in but lets no gas in or out would be an example of this type of system
Closed System
Burning wood turns it into ash, smoke, and gases; this kind of process is happening
Chemical Reaction
Describes a material that can dissolve in a particular substance, like salt in water.
Soluble
