Solids, Liquids, Gases Flashcards
What is matter?
Anything around us that has mass and volume.
Matter encompasses all physical substances.
Define mass in relation to matter.
The quantity (amount) of matter a substance or object contains.
Mass is often measured in grams or kilograms.
What is volume?
The amount of space taken up by a substance or object.
Volume can be measured in liters, cubic meters, etc.
List the three states of matter.
- Solid
- Liquid
- Gas
What is a characteristic of solid particles?
They are very close to each other.
This close arrangement gives solids a definite shape.
How do liquid particles behave?
They slide over each other.
This allows liquids to take the shape of their container.
Describe the movement of gas particles.
They move in different directions.
This movement results in gases having neither a definite shape nor volume.
What is the shape of a solid?
It has a definite shape.
Solids maintain their shape unless acted upon by an external force.
Does a liquid have a definite shape?
No, it has an indefinite shape.
Liquids conform to the shape of their container.
What is the volume characteristic of a gas?
It has indefinite volume.
Gases expand to fill the volume of their container.
What is the compressibility of solids?
Incompressible and non-expandable.
Solids cannot be compressed easily.
How do liquids behave in terms of compressibility?
Incompressible and non-expandable.
While liquids are not easily compressed, they can expand slightly.
What is the compressibility of gases?
Compressible and expandable.
Gases can be compressed significantly.
Fill in the blank: A _______ solid has a definite volume but takes the shape of its container.
pulverized
What is viscosity?
The property of liquids that resists flowing.
Higher viscosity means a liquid flows less easily.
