 What is the Archimedes Principle? the buoyant force on an object is equal to the weight of the fluid displaced by the object conjecture. What is Pascal's principle? Pressure= amount of force over the unit area P= f/a math question What is the unit of pressure? Pascal Name! What is Bernoulli's Principle pertaining to? When a fluid has to increase its velocity, you’re going to get a reduction in pressure. airplane wing Pressure of gases If pressure applied on gas pushes on g the rest of the gas behaves like the liquid conjecture Boyle's Law If you decrease the volume of a container of gas and hold the temperature constant, the pressure of the gas will increase. T is Constant take the constants out of the combined gas law to find it. P1 V1=P2 V2 combined gas law thingi and conjecture. Charles' Law the volume of a gas increases with increasing temperature, as long as pressure does not change P is K V1/T1=V2/T2 combined gas law thingi and conjecture. Gay Leussac's Law The pressure of a fixed mass at a constant volume varies directly with temperature V is K P1/T1=P2/T2 combined gas law thingi and conjecture. Combined Gas Law (P1 V1)/T1=(P2 V2)/T2 only one you need to know Hydrogen in Nature 1 proton, simply. Make-up. When the outer energy level is full, the element is . . . unreactive Noble gases Element made of the same material. no deviations Gold Compound made of two or more different elements. NaCl What makes an element? It is specifically the number of protons in an atom that define what it is. For every proton . . What does this make? There is an electron. A neutral charge. Entropy is not . . Why? Chaos Chaos connotates more Mr. B says so. Ion Any molecule or atom that has a charge Hydrogen atom in nature Hydronium ion Hydrogen ion with one proton only and w/out the electron confucius The way to express a hydronium ion. H+ abbreviation Hydronium ion Very reactive because of its single charge. Noble gases Right side of the scale NON-REACTIVE Energy levels A set space electrons occupy Average Atomic Mass Decimals Atomic Mass Rounded If you have a hydrogen atom that has a proton, and you add a neutron, it has the same charge but. . . it weighs more Isotopes same element w/ a different mass b/c they have different #s of neutrons Atomic Mass #protons+#neutrons S orbital Spherical 2 per energy level P orbital plane. 3d X-plane; Y-plane; Z-plane Energy level limits 1st energy level- fills with 2 2nd energy level-fills with 8 3rd energy level- fills with 8 4th energy level- fills with 18 D orbitals always come behind, because . . They wait for the next s-orbital to be filled. If there are more protons to hold the electrons in, the electron cloud shrinks So it's smaller than an element with less protons, but it weighs more.
