1. What is the difference between a physical and chemical change? Write your answer in complete sentences.
2. Classify the following as either a physical or chemical change:
a. Plants make sugar from carbon dioxide and water b. Water vapor in the air forms frost c. A goldsmith melts a nugget of gold and pulls it into a wire

The States of Matter
The three states of matter are: solid, liquid, and gas.
These three states of matter differ in terms of compressibility, structure, shape, and volume
Foldable Time

Kinetic Molecular Theory of Matter:
Based on the idea that particles of matter are always in motion.
Theory has 3 basic assumptions (but we are only going to cover the first 2)

Assumption #1Matter is composed of small particles (molecules)

Assumption #2
The molecules are in constant motion. This motion is different for the three states of matter.

SolidCompressibility: Not compressible
Structure: Particles are packed together in fixed position(vibrate in place)

Liquid Compressibility: more
compressible than a solid, but barely compressible
Structure: Individual molecules do not stick together(particles SLIDE past each other)

Liquid Shape: Indefinite Shape
(takes the shape of its container)
Volume: Definite Volume

GASCompressibility: Highly compressible
Structure: Gas particles do not stick together(spread out)

GAS Shape: Indefinite Shape
(takes the shape of its container)
Volume: Indefinite Volume; gases expand to fill whatever volume is available
