Chemical Change
|
The Process converting one substance into another substance that will have nw properties.
|
|
|
Dissolve
|
The process of a solid substance breaking down into a liquid state.
|
|
|
Liquid
|
The state of matter in which particles slide freely over one another. The water in the river is in a liquid state.
|
|
|
Matter
|
Somthing that has mass and takes up space
|
|
|
Physical Change
|
A change in the structure of a substance. After the change, it keeps all of its properties.
|
|
|
Product
|
The substance that comes out a chemical change.
|
|
|
Reactants
|
The substances that are used to make a chemical change
|
|
|
Solid
|
The state of matter in which paricles vibrate and do not appear to move. Ice is water ina solid state.
|
|
|
Substance
|
Any material that can be observed.
|
|
|
Weight
|
A measurement of how much Earth's gravity pulls on an object.
|
|
|
Law of Matter
|
Matter can neither be created or destroyed by ordinary means.
|
|
|
Three States of Matter:
|
Solid, Liquid, and Gas. In solids the atoms are packed closely together, in a liquid ther is more space between, and in gas the atoms have a lot of space. (Foam balls in cage)
|
|
|
Changes in Physical Properties are called:
|
Physical Changes. If the size, shape or state of a substance changes but the substance itself remains the same, then we say a physical change has occured.
|
|
|
Examples of Physical Changes
|
1.Water Freezing(weight stays the same)
2.Water evaporating from a salt water mixture 3. Paper being cut into pieces |
|
|
In Order for a Chemical Change to Occur:
|
There needs to be an unexpected change in color, heat or state
|
|
|
Examples of Chemical Changes
|
1. Adding baking soda and vinegar; weighs less because some of the matter turns into gas.
2.Heat energy burning bread 3.Rust on scissors 4.Match igniting 5.Fireworks |
