Matter
Name the four forms of matter found on Earth
Solids, liquids and gases
Everything on the left side of the equation is called
reactants
The substance doing the dissolving is the
solvent
energy travels in
waves
name the tool used to measure length and what unit of measure we use.
Ruler--centimeters
What are three properties you could use to describe matter
Everything on the right side of the equation is called
products
The substance being dissolved is the
solute

wavelength
What unit of measure do we use to measure mass?
grams
Define the difference between a solid, a liquid and a gas.
A solid keeps its shape, a liquid takes the shape of the container and a gas goes everywhere.

False
What two components make a solution?
solute + solvent
When you look in the mirror you see your
reflection
What unit of measure do we use to measure volume?
milliliters
What does it mean when something evaporates?
It changes from a liquid to a gas.
The mass of the reactants is ten. What is the mass of the products?
10
A solution that can dissolve more solute is called
unsaturated
In order to travel, sound needs a
medium
You use this item to measure the mass
