818Compare the particle
arrangement and type of particle motion associated
with different states of matter.
Compare the particle arrangement and type of particle motion associated with
different states of matter.Key concepts/skills:Level 1: Define solid, liquid, gas. Describe particles that make up matter (atoms and molecules) and how they are all in motion.Level 2: Compare the particle arrangement and motion of different states of matter.Level 3: Explain how the amount of thermal energy determines states of matter. Define thermal energy, freezing point, melting point, boiling point, condensation, and vaporization.

Compare the particle arrangement and type of particle motion associated with
different states of matter.
I. States of matterA.Solid
1.definite shape (shape does not change)
2.definite volume (always take up same amount of space)
3.particles densely packed4.Very strong bonding forces
Compare the particle arrangement and type of particle motion associated with
different states of matter.
B. Liquid 1.no definite shape2.definite volume3.particles close4.strong bonding forces
Compare the particle arrangement and type of particle motion associated with
different states of matter.
C. Gas1.no definite shape2.no definite volume3.particles far apart4.weak bonding forces
Compare the particle arrangement and type of particle motion associated with
different states of matter.
II. Particle MotionA.Solid – the bond between the particle keeps the
particles from moving very muchB.Liquid – the bonds between particles are
strong but allows for more movement than in solids C. Gases – the bonds between the particles are weak allowing the particles to move freely
Compare the particle arrangement and type of particle motion associated with
different states of matter.III. Heat and State of Matter
A. Thermal Energy – heat energy that, when added to objects, can control their state of matter
B.Adding thermal energy1.Melting – heat is added to a solid allowing
particle motion to become stronger than bonding forces/ the solid becomes a liquid
2.Vaporization – heat is added to a liquid allowing particle motion to become greater than bonding forces/ the liquid becomes a gas (boiling point)
Compare the particle arrangement and type of particle motion associated with
different states of matter.B. Removing Thermal energy• Condensation – heat is removed
from a gas causing the bonding forces to be greater than the particle motion / the gas becomes a liquid
1. Freezing – heat is removed causing the bonding forces to be much greater than particle motion/ the liquid becomes a solid
