Absolute pressure….it is the actual pressure at given position ..relative.. vacuum.
Boundary...it is the real or imaginary surface that separates the system from its surroundings.
Classical thermodynamics...it`s the macroscopic approach to the study of thermodynamic that does..behavior of individual particles.
Closed system...consists of a fixed amount of mass, and no mass can cross itboundary. But energy, form of heat, can cross the boundary.
Conservation of mass principle...it expresses that a net mass transfer to or from a control volumen..the control volume during the time interval.
Control Volume...it is any arbitrary region in space throught which mass and energy.
Cycle...it`s a process, or series of processes, that allows a system to undergo state changes and returns thesystem.
Entropy...measure of molecular disorder, or molecular randomness.
Extensive properties...are those whose values depend on the size of the system.
First law of thermodinamic...it is a simply a statement of conservation of energy principle..it can only change forms.
Gage pressure...it`s the difference between the absolute pressure and the local atmospheric.
Heat transfer...it`s defined asthe form of energy that is transferred between two systems.
Intensive properties...are those that are independent of the size of a system, such as temperature, pressure.
Mass of a system...it`s equal to the product of its molar mass M and the moles number N.
Mechanical equilibrium...it`s related to pressure, and a system undergoes from one equilibrium if there is no change in pressure.Process...it`s any change that a system undergoes from one equilibrium state to another.
Property...it`s any characteristic of a system.
Quasi-static...process is a process which proceeds in such a manner that the system remains infinitesimally..process that allows the system to adjust itself internally.
Second law of the thermodynamics...is expressed as the entropy of a isolated system during aprocess always..the entropy of an isolated system never decreases.
Simple compressible system...it`s a system in which there is the absence of electrical magnetic, tension effcts.
Thermal equilibrium...means that the temperature is the same throughout the entire system.
Thermodynamic system...or simply a system, is defined as a quantity of matter or a region in space chose for study.Thermodynamics...it`s the scien of energy.
Third law of thermodynamics...it states that the entropy of a pure crystalline substance at absolute zero temperature is zero.
Vacuum pressure...it`s the pressure below atmospheric pressure.
Zeroth law of thermodynamics...it states that if two bodies are in thermal equilibrium with a thrid body.
Thermodynamics...sciene that primarily deals withenergy..transformatios, including power generation and realationships among the properties of matter.
Apprenticeship...is a system of training a new generation of skilled crafts practitioners.
Commentator...a person who makes commentaries.
Drill press...it`s fixed style of drill that may be mounted on a stand or bolted to the floor or worbench.
Entrepreneurs...a person who organizes, operates.
Fair trade...it`san organized social movement and marketbased approach to elleviating global poverty and promoting sustainability.
Firm...a partherships or association for carrying on a business.
Guild...it`s an association of craftsmen in a particular trade. The earlinest guilds were formed..
Handicraft...also know as craftwork or simply craft, is a type of work where useful and decorative devices
In dustrialrevolution...was a period in the late 18th and early 19th centuries..
Kilns... they are thermally insulated chamerts, or ovens, in which controlled temperature..
Lathe...it`s a machine tool wich spins a block of material to perform various
Manufacturing...it`s the use of tools and labor to make things for use or sale.
Milling machine...it`s a machine tool used for the complex shaping of...
