Term
hydraulic system
Definition
a hydraulic system is a drive or transmission system that uses pressurized hydraulic fluid to power hydraulic machinery
Term
hazard symbol
Definition
when a symbol lets you know that it is a hazard to your body like poisonis
Term
WHMIS
Definition
it is a comprehensive plan for providing information on the safe use of hazerdous materials.
Term
hydrometer
Definition
an instrument used for measuring the density of liquid.
Term
pneumatic system
Definition

is a branch of physics applied to technology that makes use gas or pressurized air

Term
pure substance
Definition

a material that is composed of only one type of particle

Term
mixture
Definition

a substance made by mixing other substances together

Term
mechanical mixture
Definition

a heterogeneous mixture of particles or masses distinguishable as such under the microscope or seperable by filteration

Term
hetergeneous mixture
Definition

a hetergeneous mixture is simply any mixture that is not uniform in composition

Term
homogeneous mixture
Definition

a mixture which has uniform composition and properties throughout

Term
solution
Definition

a liquid mixture in which the minor component is uniformaly distributed with a major component

Term
suspension
Definition

a mixture in which particles are dispursed throughout the bulk fluid

Term
colloid
Definition
a homogeneous, noncrystalline substance concisting of large molecules or ultramicroscopic particles of one substance desperced through a second substance
Term
solute
Definition
the minor component in a solution, dissolved in the solvent.
Term
solvent
Definition
able to dissolve other substances
Term
concentration
Definition
the relative amount of a given substance contained within a solution or in a particular volume of space; the amount of solute per unit volume of solution
Term
unsaturated solution
Definition
 An unsaturated tea and sugar solution would be one into which you could add more sugar and have the sugar still dissolve
Term
saturated solution
Definition
containing the greatest possible number of hydrogen atoms, and so having no carbon–carbon double or triple bonds.
Term
solubility
Definition
is the mathematical product of its dissolved ion concentrations raised to the power of their stoichiometric coefficients
Term
saturation point
Definition
 
 
    • the stage beyond which no more of something can be absorbed or accepted.
Term
aqueous solution
Definition
An aqueous solution is a solution in which the solvent is water.
Term
particle model of matter
Definition
All matter is made up of particles that are much too small to be seen. Theparticles are always in motion.
Term
viscosity
Definition
the state of being thick, sticky, and semifluid in consistency, due to internal friction.
Term
density
Definition
degree of consistency measured by the quantity of mass per unit volume.
Term
buoyant force
Definition
is an upward forceexerted by a fluid that opposes the weight of an immersed object
Term
buoyancy
Definition
the ability or tendency to float in water or air or some other fluid.
Term
incompressible
Definition
t able to be compressed.
Term
pressure
Definition
the continuous physical force exerted on or against an object by something in contact with it.
Term
Pascal’s Law
Definition
Pascal's law or the principle of transmission of fluid-pressureis a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations
Term
pump
Definition
a mechanical device using suction or pressure to raise or move liquids, compress gases, or force air into inflatable objects such as tires
Term
valve
Definition
a device for controlling the passage of fluid through a pipe or duct
