Phases of matter and how they change

Matter is made of particles The three phases of matter are: Solid Liquid Gas Which they are depends on how tightly packed they are

Matter and the Particle model Matter has mass mass= # of particles Matter has volume Volume= the space between the particles This is the title of your foldable Cut it out and glue it to the top right of the construction paper

State or Phase solid low energy Cut out this strip. Fold it in half Glue it to the right middle of construction paper Open up the paper

On the left side Draw this picture

On the right side Definite volume Properties Mass lots of particle Volume particles are packed close together Definite volume Density most dense Bonds particles are tightly bound together Shape they have a definite shape Speed particles only vibrate

State or Phase liquid medium energy Cut out this strip. Fold it in half Glue it to the right middle of construction paper Open up the paper

On the left side Draw this picture

On the right side Definite volume Properties Mass medium amount of particles Volume particles have a little space between them Definite volume Density less dense than solids more dense than gas Bonds particles are loosely bound together Shape takes the shape of the container Speed particles move a little bit

State or Phase gas high energy Cut out this strip. Fold it in half Glue it to the top left of construction paper Open up the paper

On the left side Draw this picture

On the right side No Definite volume Properties Mass very few particles Volume particles lots of space between them No Definite volume Density least dense Bonds no bonds between particles Shape takes the shape of the container Speed particles fly around fast

Phase changes Or how does water go from a solid to a liquid to a gas? Add Heat How does water go from a gas to a lquid to a solid? Take away heat These changes can happen with any kind of matter Gold iron air helium alcohol Nail polish remover Each od these changes has a special name.

Phase changes that require heat to be added Cut out the add heat arrows Colour them red (one is upside down that’s good) Fold them in half Glue them down so that they link the phases Solid  liquid Open it up and on the inside write fusion or melting Solid  gas Open it up and on the inside write sublimation Liquid gas Open it up and on the inside write vaporization

Phase changes that require heat to be removed Cut out the Take away heat arrows Colour them blue (one is upside down that’s good) Fold them in half Glue them down so that they link the phases gas  liquid Open it up and on the inside write condensation Gas  Solid Open it up and on the inside write deposition Liquid solid Open it up and on the inside write solidification or freezing

What phase change is this? Jack frost painting pictures on your window in winter. Dew on the grass is the morning. Water on the outside of your cold glass of lemonade. Melting ice cream. Heating water in a teakettle until it boils. “Fake smoke” in the movies. Iodine crystals turning into purple gas. Liquid silicon turning into glass. Hardening liquid steel.
