msheerin17 : thank you scullen for the cards
msheerin17 : Thank you scullen
Alex_Gottlieb : Thanks MR. SEAMUS
scullen : who is hotwater
scullen : hot water is a 7TH GRADER!!! :0
SagePhilip : who?
scullen : hotwater
scullen : no idea who i checked the account it is hard to tell who everything is locke
scullen : i think sophia based on data i could arrive @
hotwater : yeah, i'm matt. Ian showed me the set and i wanted to see what you were learning with mr.fitzroy in science
msheerin17 : why hotwater?
hotwater : idk, i've had that handle for a while. it started on ICC (those of you who play chess should know what that is)
Alex_Gottlieb : no way iain
Shenwen8 : Thank you scullen!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
scullen : welsome stevey wonder
scullen : no offense to anyone but... YOU GUYS ARE OBSESSED
roilior : hi everyone
roilior : i have been working on this for so long
roilior : bob
roilior : sorry, i meant to type that somewhere else
msheerin17 : thanks again scullen
scullen : welcome ol chap
msheerin17 : r u still on?
msheerin17 : ha ha
scullen : no idea
scullen : :0
scullen : :l
msheerin17 : yello
hotwater : there are so many emoticons. and more
msheerin17 : lior are you on?
sagealli : these flash cards really helped seamus
scullen : tweet

 PascalThe unit in which scientists measure pressure

#### Definitions

Pascal The unit in which scientists measure pressure
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
Pressure-Temperature Relation When temperature raises neer a container the fluid expands but since the cansiter is rigid pressure builds until explosion.
Charles's Law The volume of a gas increases with increasing temperature, as long as pressure does not change.
Buoyancy The ability for a fluid to exert an upward force on an object immersed in it
Fluid A liquid or gas
Pressure Force exerted per unit area
Pressure equation P=F/A
Pascal's Principle Pressure applied to a fluid is transmitted throughout the fluid.
Bernoulli's Principle As the velocity of the fluid increases,the pressure of the fluid decreases
Viscosity The resistance to flow by a fluid
Kinetic Theory An explanation of how particles behave
Thermal Energy The total energy of a materials particles including kinetic
Kinetic Energy Vibrations and motions within and between particles
Potential Energy Resulting from forces that act within or between particles
Melting Point The temperature at which a solid begins to liquify
Heat of Fusion The amount of energy required to change a substance from a solid to a liquid at its melting point
Boiling Point The temperature at which the pressure of the vapor is equal to the external pressure resulting in a change of state from liquid to gas
Heat of Vaporation The amount of energy required for a liquid at its boiling point to become a gas
Diffusion The spreading of particles throughout a given volume until they are uniformly distributed.
Plasma Matter consisting of positively and negatively charged particles
Solid A state of matter that has a geometric arrangement and the particles are closely packed
Liquid A state of matter taht has no fixed geometric shape but a fixed volume. Particles move freely
Gas A state of matter at which the particles are far apart and overcome their attractive forces. No fixed shape or volume
Thermal Expansion An increase in the size of a substance when the temperature is increased. An exception is water.
Contraction The decrease in the size of a substance when temperature is decreased
Amorphous Solids A solid that has no melting point and melts over a period of time
freezing point the temperature at which a liquid freezes and turns solid
distillation the process of separating substances by evaporating the liquid and condensing its vapor
substance something with a fixed composition. (NOT AT TYPE OF MATTER!!)
element A substance in which all the atoms are the same
compound a substance in which all the atoms of 2 or more elements are combined in a fixed proportion.
suspension a heterogeneous mixture containing a liquid that has visible particles that settle
hardness a measure of how easily a mineral can be scratched
mohs scale a scale of hardness of solids
conservation of mass over time, mass cannot be created nor destroyed
chemistry the structure of the chemicals that make up a substance
mixture a compound with no specific proportions. It can also be separated.
homogeneous mixture 2 substances blended evenly throughout a mixture.
heterogeneous mixtures A mixture in which the substances can be easily identified
luster property of metals and alloys that descibes having a shiny appearence or reflecting light.
sublimation the process of a solid changing directly to a vapor without forming a liquid.
solubility maximum amount of a solute that can be dissovled in a given amount of solvent at a given temperature.
malleable ]the ability of metals and alloys to be rolled or hammered into thin sheets
ductile the ability of metals to be drawn into wires
physical property Any characteristic of a material that you can observe without changing the identity of the substances that make up the material.
physical change A change in shape, size, or state.
chemical property A characteristic of a substance that indicates if it can undergo a certain chemical change.
Colloid A type of mixture with particles that are larger than those in solutions, but not heavy enough to settle out.
Solution A homogeneous mixture of particles they cannot be seen with a microscope and will never settle to the bottom of their container.
Tyndall Effect a beam of light is invisible as it passes through a solution, but can be seen readily as it passes through a colloid.
chemical change A change from one substance to a new substance
separation Distinguishing substances from each other using physical properties
pure substance something with a fixed composition
number of elements There are 103 different kinds of elements. 90 elements can be found on earth, and 20 can be produced in laboratories.
states of matter solid, liquid, gas, and plasma
Seperation techniques distillation, sifting, and magnetism.
