Term
Hydraulic System
Definition
system that uses a liquid under pressure to mover loads
Term
Hazard Symbol
Definition
Harzard Warning
Term
WHMIS
Definition
Workplace Hazardous Materials
Information System
Term
hydrometer
Definition
A hydrometer is an instrument used to measure the specific gravity
Term
pneumatic systems
Definition
Pneumatic systems used extensively in industry are commonly powered by compressed air or compressed inert gases.
Term
pure substance
Definition
A material that is composed of only one type of particle
Term
mixture
Definition
a mixture is a material system made up of two or more different substances which are mixed but are not combined chemically
Term
mechanical mixture
Definition
A heterogeneous mixture of particles or masses distinguishable as such under the microscope or separable by filtration.
Term
heterogeneous mixture
Definition
A heterogeneous mixture is a mixture that composes of components that aren't uniform or they have localized regions that all have different properties
Term
homogeneous mixture
Definition
A homogeneous mixture has the same uniform appearance and composition throughout.
Term
solution
Definition
a solution is a homogeneous mixture composed of two or more substances.
Term
suspension
Definition
suspension is a heterogeneous mixture containing solid particles that are sufficiently large for sedimentation.
Term
colloid
Definition
A colloid is a solution that has particles ranging between 1 and 1000 nanometers in diameter,
Term
solute
Definition
the minor component in a solution, dissolved in the solvent.
Term
solvent
Definition
a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution
Term
concentration
Definition
concentration is the abundance of a constituent divided by the total volume of a mixture.
Term
unsaturated solution
Definition
The solvent for the ocean is water, a liquid, and salt is the solute.
Term
saturated solution
Definition
saturation is the point at which a solution of a substance can dissolve no more of that substance and additional amounts of it will appear as a separate phase (as a precipitate[2] if solid or as effervescence or inclusion if gaseous).
Term
solubility
Definition
Solubility is the property of a solid, liquid, or gaseous chemical substance called solute to dissolve in a solid, liquid, or gaseous solvent to form a solution of the solute in the solvent
Term
saturation point
Definition
the stage at which no more of a substance can be absorbed into a vapor or dissolved into a solution.
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. The particles are always in motion.
Term
viscosity
Definition
The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.
Term
density
Definition
Density is a characteristic property of a substance.
Term
buoyant force
Definition
BUOYANT FORCE - ARCHIMEDE'S PRINCIPLE. When a rigid object is submerged in a fluid (completely or partially), there exits an upward force on the object that is equal to the weight of the fluid that is displaced by the object.
Term
buoyancy
Definition
is an upward force exerted by a fluid that opposes the weight of an immersed object.
Term
compressibility
Definition
n thermodynamics and fluid mechanics, compressibility is a measure of the relative volume change of a fluid or solid as a response to a pressure (or mean stress) change.
Term
incompressible
Definition
incompressible flow (isochoric flow) refers to a flow in which the material density is constant within a fluid parcel—an infinitesimal volume that moves with the flow velocity.
Term
pressure
Definition
is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
Term
Pascal’s Law
Definition
Pascal's law or the principle of transmission of fluid-pressure (also Pascal's Principle) is 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
where something is being pushed to a place
Term
valve
Definition
a cylindrical mechanism in a brass instrument that, when depressed or turned, admits air into different sections of tubing and so extends the range of available notes.
