Presentation on theme: "States of Matter A. The Kinetic Theory"— Presentation transcript:
1States of MatterA. The Kinetic Theory1. All matter is composed of small particles (atoms, molecules, or ions).2. They are in constant, random motion.3. They constantly collide with each other and with the walls of their container.
3C. Other States1. Solids with particles in repeating geometric patterns are crystals. Those with particles arranged randomly are amorphous.2. Plasmaa. Hot, ionized gas particles.b. Electrically charged.c. Most common state in universe.
4D. Thermal E x p a n s i o n1. Particles in any state expand when heated (generally).2. Examples of solids:a. Expansion jointsb. Power linesc. Thermostats3. Different materials expand at different rates.
54. Mercury and alcohol are liquids that expand in thermometers 5. Air expands when heated (becoming less dense)6. Water reaches maximum density at about 4 C.Ice particles are farther apart than liquid water (so it floats).
