Chemistry is the study of
________________
Matter
The three common types of matter on Earth are_______,_______, and _________.
Solid, liquid, and gas
Matter is defined as…
Anything that has mass and takes up
space
The particles of matter are called…
Molecules
The molecules of this type of matter are attracted to each other, but able to move past each other.
Liquids
When the particles of a liquid are heated, what happens to the speed and space between the particles?
The particles increase in speed and increase in space
Cooling a liquid _______ the speed of the molecules and _______ the space between them.
decreases and
decreases
This is diagram of room-temperature water.
Draw the particles of cold water and hot water.
Gas is matter
because it…
takes up space and has mass
The molecules of gases are ____________ apart and have a weak _____________ to each other.
farther attraction
Particles of gas move _______ and barely _______ each other.
quickly
touch
Heated gases will make the molecules move ________ and hit the container holding it ________.
fasterharder
When gas molecules are cooled they move _______ and do not _______ as hard against the container.
Slower
push
Draw gas moleculesat room temperature.
The molecules of a solid are_______ to each other and _________, but do not _____past one another.

When a solid is heated the molecules vibrate _______ and move slightly _______ apart.

What happens to a solid that is cooled?
The molecules vibrate slower and pull closer together.
Draw a diagram of each type of matter at room temperature.
