Intro Things to know

chem and phys

chemistry the study of composition, structure, properties, and reactions of matter
convection transphers by currents with fluid. (boiling water, air current, heating of a room
friction a force that opposes the motion of objects that touc h as they move past each other( can transpher electrons through this)
atomic number number of protons(gives you number of electrons as well). gives you protons in an atom
nutron has no charge in found in the nucleus. subtromical particle
density the ratio of a material's mass to it's volume
celcius freezing point is zero, boiling point is 100
alloy a mixture of two or more elements at least one which is metal, that has charecteristics properties of metals
mass number the sum of the protons and neutrons in the nucleus
atomic mass unit one twelth the mass of a carbon -12 atom(AMU)
acid a coumpound that produces hydronium when dissolved in water, a protondonor.
farhenhit. freezes at 32 degress, boils at 212 degress
dissolving a breakdown of cystal
frequency the number of complete cycles per unit of time for a periodic motion
length the straight line distance between two points
base a coumpound that produces hydroxide ions. When dissolved in water; a proton accepter.
matter has mass which encludes atoms and other particles
physics the study of matter and energy and the interactions between the two forces of motion
barometer instrument used to messure atmospheric pressure. (Uses water, air, and mecury)
boiling when vapor and pressure in equal to atmospheric pressure
inertia the tendency of an object to resist a change in motion
ionic kind of bonding where an atom shares its electrons as the other atom gains electrons when bonding. Is always metals with non-metals.
compound a substance that is made from 2 or more simpilier substances and can be broken down into simplier substance
mass the amount of matter in an object
salt ionic compound. formed when acids react with bases
evaporations happens when temperature is below substances boiling point
covalent bonding when they do not share atoms equally( is always non metals with non metals)
weight the force of gravity acting on an object
gravity the attraction between two any 2 objects because of their masses
condinsation the phase change in which a substance changes from a gas or vapor to a liquid. (think of clouds raining)
radioactivity the process in which an unstable atomic nucleus emits charged particles and energy( think of clouds setting of electricity or lighting)
Galileo studies how gravity produces constant acculation, moving objects not subject to friction would continue to move indefineity.
Newton built work on scientist. Came up with laws of motion. Law of Inerertia: a state of a motion of an object will not change as long as force acting on the object is zero 2nd Law: acceleration of an object is equal to the net force acting on it divided by o
Einstein law of relativity: came up with two ways to measure mass with same value
Curie discovered the radioactivity elements radium and polonium advance study of radio activity
Law of Matter matter cannot be created nor destroyed in an isolated system
Chemical equations. chemical reaction in which the reactions and products are expressed as formulas
atomic mass the electrons and protons added together( when subtracted will give you your neutrons)
