Let's start at the beginning...
What is Physical science?
The study of matter and energy
What is an atom?
The smallest particle into which an element can be divided
What are the 4 states of matter?
Solid, liquid, gas and plasma
Define Physical Property.
without changing the identity of a substance
NaCl?
Table salt
What is matter?
The "stuff" everything is made of.
When an atom gains or loses electrons, it is called a...?
An ion
What is kinetic theory of mater?
Matter made up of particles which are in continual random movement
Density equals mass over volume (D=m/v)
What is Fe and Zi?
Iron and Zinc
What is energy?
The ability to work
Atoms with different numbers or protons and neutrons can become unstable and are called radioactive.

What branch of physical science is the study of all matters?
Chemistry
Where does the atom's mass and volume come from?
An atoms mass comes from the protons and neutrons and the atoms volume is due to the electron cloud.
What has an indefinite shape but a definite volume?
Liquid
What are the changes in state?
Freezing, boiling, condensation. and evaporation
Pure substances that cannot be separated into simpler substances by physical or chemical means.
Elements
What branch of physical science explains the ways energy affects matter; this includes motion, force, gravity, electricity, light and heat?
Physics
The atoms are joined by the outer ring of electrons.
Valence electrons.
Name the following changes in a matter:
Solid to a liquid.
Liquid to gas.
