Fluid
answer
Flows, and has no definite shape.
question
Pressure
answer
Force divided by surface area.
question
Archimidies Principle
answer
States that the magnitute of the buoyant force on an object equals the weight of fluid displaced by the object.
question
Plasma
answer
A gas-like state that contains electrons, and positively charged ions.
question
Pascal
answer
The SI standard unit of pressure.
question
Combined Gas Law
answer
States that for a fixed amount of ideal gas, the pressure times the volume devided by the kelvin temperature equals a constant.
question
Crystal Lattice
answer
A fixed pattern of particles with a solid.
question
Ideal Gas Law
answer
PV=nRT
question
Buoyant Force
answer
Upward force on an object immersed in a liquid
question
Bernoulli's Principle
answer
As velocity of a fluid increases the pressure exerted by the fluid decreases
question
Thermal Expansion
answer
An increase in temerature produces an increase in the volume of matter and a decrease in density
question
Cohesive Forces
answer
Electormagnetic attractions of particles within a substance for one another
question
Coefficient of linear expansion
answer
Change in length divided by the original length and the change of temperature
question

answer
change in pressure at any point on a confined fluid transmited undiminished through the fluid
question
Adhesive forces
answer
attractive forces between particles of different substances
question
Amorphous Solid
answer
definite volume and shape but no regular crystal structure
question
Streamlines
answer
flow of fluids around objects
question
Coefficient of volume expansion
answer
change in volume divided by original volume and change in temperature
