1
Phases of Matter AKA States of Matter
2
Three Plus One Solid Solid Liquid Liquid Gas Gas plus Plasma plus Plasma
3
Summarizing the Properties of Solids Maintain a regular shape Maintain a regular shape Have a Definite volume Have a Definite volume Particles are closely packed Particles are closely packed Particles vibrate—in place. Particles vibrate—in place.
4
Summarizing the Properties of Liquids Takes the shape of its container Takes the shape of its container Has a Definite Volume Has a Definite Volume Particles vibrate and slide in and our among each other Particles vibrate and slide in and our among each other Particles are packed close to each other Particles are packed close to each other
5
Summarizing Properties of Gases Particles take the shape of the container Particles take the shape of the container Particles expand to fill available space. Particles expand to fill available space. Particles are far apart (relatively speaking) Particles are far apart (relatively speaking)
6
Plasmas—The Fourth State Much like gases Much like gases Particles are electrically charged Particles are electrically charged –Ions –Electrons Exist as a result of high energy Exist as a result of high energy –Stars –Neon tubes and fluorescent tubes –Auroras
7
Define in terms of changing states of matter
8
Melting
