1. Chemistry Review

2. atom extensive Physical property
The smallest unit of an element that maintains the chemical identity of that element.
These properties depend on the amount of matter that is present.
This is a characteristic that can be observed or measured without changing the substance.

3. Chemical change plasma mixture
A change in which one substance is converted into a new substance.
A state of matter which is high temperature in which atoms lose most of their electrons.
A blend of two or more kinds of matter each retaining their own characteristics.

4. Heterogeneous mixture
This type of matter has a fixed composition. An example is nitrogen, sucrose, and water.
This type of mixture shows its separate parts.
This state of matter has a fixed volume and fixed shape. Its particles are close together and do not move much.

solid

5. liquid gas Physical change
This state of matter has a fixed volume, but not a fixed shape.
This state of matter does not have a fixed volume or shape.
Changes of state is an example of this type of change.

6. These properties or characteristics do not depend on the amount of matter present.
A measure of the amount of matter in an object.
Anything that has mass and takes up space.

7. Intensive and physical
Melting point, density, ability to conduct electricity are examples of this type of property.
Color, change of state, grinding a solid, cutting a solid in half are examples of this type of change.
Volume, mass, energy are examples of this type of property.
