Question | Answer |
---|---|
Boyle's Law | P and V (inverse) |
Charles' Law | V and T (direct) |
Viscosity | measurement of the flow properties of a matterial expressed as it's resistance to flow |
Density | ratio of mass of an object to its volume (D is equal to M divided by V) |
Ruther Ford | Nucelus: atoms mostly empty space w/ majority of mass in the center |
Nucelus | Positve charge |
Thomson | Electrons (cathode ray) |
Chadwick | Neutrons |
Goldstein | Protons |
Dalton's laws no longer true | 1. Atoms were indivisible 2. Atoms are identical |
Left to right on the periodic table | Increasing in amount of energy needed to remove valence electrons |
Bottom to top | Increasing in amount of energy needed to remove valence electrons |
Longer the wave length | closer to red |
Little frequency | closer to red |
Little energy | closer to red |
Stars Life Colors | Blue to Red |
Metals are... | malleable because they have positive ions (low ionization) |
Saturated | no more solute dissolves |
Unsaturdated | more dissolves |
Supersaturated | added crystals grows |
Solubility | ability to dissolve |
Contributors in solubility... | temperature, surface area, and stirring |
exothermic | release of energy (heat) ex: freezing, condensation |
endothermic | absorb energy (heat) ex: melting, evaporation |
Dmirtri Mendelleve | columns in order by increasing atomic mass (they have common properties |
intensive | doesn't change (color, melting pt., boiling pt.) |
extensive | changes with amount (volume, mass, etc.) |
isotopes | atoms with same atomic number but different masses (neutrons) |
fusion | combining |
fission | splitting |
