What is matter? Anything that has mass and occupies space is called Matter.

CHANGE IN MATTER
Water can change from one state to another by adding or subtracting heat.
A solid changes to a liquid when heat is added.
What are States of Matter? States of matter are the distinct forms that different phases of matter take on. Solid, liquid and gas are the most common states of matter on Earth. Historically, the distinction is made based on qualitative differences in bulk properties. Solid is the state in which matter maintains a fixed volume and shape; liquid is the state in which matter maintains a fixed volume but adapts to the shape of its container and gas is the state in which matter expands to occupy whatever volume is available.
States Of Matter
The Three States of Matter
Basis of Classification of the Three Types
Based upon particle arrangement
Based upon energy of particles
Based upon distance between particles
States of Matter The Three States of Matter Solid Liquid Gas Solid Liquid Gas
A solid is matter that has that has definite size and shape.
Example: Put a sneaker in a box. It stays the same.
Solids hold their shape.
Ice and snow are examples of water in the solid state.
Particles of solids are tightly packed, vibrating about a fixed position.
Solids have a definite shape and a definite volume.
Solids have an infinite number of free surfaces.
Properties of Solids
Solids have a definite shape and a definite volume because the particles are locked into place
Solids are not easily compressible because there is little free space between particles
Solids do not flow easily because the particles cannot move/slide past one another
Particles of liquids are tightly packed, but are far enough apart to slide over one another.
Liquids have an indefinite shape and a definite volume.
Liquids have one free surface.
When we think of water, we usually think of water as a liquid. A liquid will take the shape of whatever container it is in.
We drink liquid water. We swim in liquid water.
A liquid changes to a solid when you take away heat, or it gets colder.
Our lakes and rivers are filled with water.
Properties of Liquids
Liquids have an indefinite shape because the particles can slide past one another.
Liquids are not easily compressible and have a definite volume because there is little free space between particles.
Liquids flow easily because the particles can move/slide past one another.
Particles of gases are very far apart and move freely.
Gases have an indefinite shape and an indefinite volume.
Gases have no free surfaces.
Gas is matter that has no definite shape. Gases take the shape of whatever container they are in .
Example: The air all around us is a gas.
Water vapour is an invisible gas that is always in the air.
Clouds are made up of water vapour.
Steam floating up from the sidewalk after the rain or from a hot bowl of soup is water vapour.
Properties of Gases
Gases have an indefinite shape and an indefinite volume because the particles can move past one another.
Gases are easily compressible because there is a great deal of free space between particles.
Gases flow very easily because the particles randomly move past one another.
