23. States of Matter
• Solids• Liquids• Gases• Plasma
![Page 25: Exam Review Know the parts of the periodic table. (Group names) Know the prefixes.](https://reader031.fdocuments.us/reader031/viewer/2022032312/56649e1c5503460f94b0a43c/html5/thumbnails/25.jpg)
24. State changes
Solid Liquid Gases PlasmaParticles are arranged closely in solids as
heat is added they start moving faster and spread apart gases
The faster particles move, the more energy involved
K inetic Theory

25. Archimede’s, Bernoulli’s and Pascal’s Principles
• Archimide’s: Buoyancy (buoyant force and weight)
• Bernoulli’s: as velocity of a fluid increases, the pressure decreases– Ex. Airplane technology, roofs lifted during
tornadoes
• Pascal’s: Pressure applied to a fluid is transmitted throughout the fluid– Ex. Toothpaste tube
![Page 27: Exam Review Know the parts of the periodic table. (Group names) Know the prefixes.](https://reader031.fdocuments.us/reader031/viewer/2022032312/56649e1c5503460f94b0a43c/html5/thumbnails/27.jpg)
26. Charles’ and Boyle’s Laws
• Charles: The volume of a gas increases with increasing temperature.–Pressure stays constant here–Gas expands as it is heated–Ex. Hot air balloon
• Boyles: if you decrease volume of a container of gas, the pressure of the gas will increase–Temperature stays constant here
![Page 28: Exam Review Know the parts of the periodic table. (Group names) Know the prefixes.](https://reader031.fdocuments.us/reader031/viewer/2022032312/56649e1c5503460f94b0a43c/html5/thumbnails/28.jpg)
27. Kinetic Theory
• All matter is composed of small particles• These particles are in constant, random
motion• If you increase the temperature,
particles move faster.• If you decrease the temperature,
particles move slower.

28. Subatomic Particles
• Nucleus–Protons: Positive–Neutrons: Neutral
• Electron Cloud–Electrons : negative
![Page 30: Exam Review Know the parts of the periodic table. (Group names) Know the prefixes.](https://reader031.fdocuments.us/reader031/viewer/2022032312/56649e1c5503460f94b0a43c/html5/thumbnails/30.jpg)
29 & 30. How do subatomic particles affect properties of an atom?
• Nucleus: gives atom its mass– Mass number = protons + neutrons
• Protons: (atomic number) – Identity
• Electrons: give the atom its chemical properties– Ionic and Covalent Bonding
![Page 31: Exam Review Know the parts of the periodic table. (Group names) Know the prefixes.](https://reader031.fdocuments.us/reader031/viewer/2022032312/56649e1c5503460f94b0a43c/html5/thumbnails/31.jpg)
31. Compare/contrast atoms of elements which exist as stable or unstable isotopes.
• Isotopes: atoms of the same element with different numbers of neutrons.
• Ex. Carbon-12 & Carbon-14 are both isotopes of Carbon
• Carbon – 12 is stable
