What’s a
MATTER?Chapter 2
Pre-requisite
Anything that has mass and
takes up space!A. Definiton:
B. The Law of Conservation of Matter: by Antoine LaVoisier
Matter is neither created nor destroyed yet
converted from one form to the next.
C.C. The states of Matter?The states of Matter? SolidSolid

D. One Factor that can affect the state of matter is: Temperature
If I increase it, how will the state change?
The molecules Kinetic Energy increases.Kinetic Energy = Energy in motion
1. Celsius: Andres Celsius (1701-1744)
C= F-32 1.8
2. Fahrenheit: Gabriel Fahrenheit; (1686-1736)
3. Kelvin: The International system of Units (SI); William Thomson Lord Kelvin (1824-1907)
F=C X1.8+32F=C X1.8+32
K= K= ooC + 273C + 273
VI. Temperature Scales
Freezing water: 0oCBoiling water: 100oC
Freezing water: 32oFBoiling water: 212oF

K = oC + 273 oC = K - 273
C= 310-273
K= 25 + 273
C= F- 32

C= 75- 32

K= 24+ 273
= 24 oC
ABSOLUTE ZERO: 0K is = -273ABSOLUTE ZERO: 0K is = -273ooC. C.
The point at which the motion of The point at which the motion of particles of matter ceases (STOPS)!! particles of matter ceases (STOPS)!!

STOP here!!
Changes in Matter can be Changes in Matter can be physical or chemicalphysical or chemical
A.A. Physical change:Physical change: Identity of Identity of substance substance is is NOT altered.NOT altered.
B.B. Chemical change:Chemical change: New substance New substance has has different set of different set of
properties.properties.

C. Forms of Matter
a. Element: Smallest, indivisible part of a substance
b.Compound:
When a metal and nonmetal combine by giving and taking
electrons!
Ex: Table salt
c. Molecule: When two or more nonmetals combine by sharing electrons!!
Ex: Water (H2O)
d. Mixture:
i. Homogeneous Mixture:
Visible components are all similar
d. Continuation w/Mixtues
ii . Heterogeneous Mixture:
Has visible distinction between parts
Yeah!Yeah!
Done with the Done with the
pre-requisite stuff!pre-requisite stuff!
