A closed system is a system in which matter and energy are not exchanged with the surroundings. Explanation: A closed system is a physical system that does not interact with other physical agents located outside it and therefore is not connected casually or related to anything external to it.
Example: He was aware of the speculative nature of much of his work, and of the need in people to foreclose his work into a CLOSED SYSTEM

conduction
noun
Heat conduction (or thermal conduction) is the transfer of energy from a hotter substance to a cooler one through direct contact, such as when someone touches the handle of a hot metal pan.
Example: CONDUCTION along the walls is negligible Potential and kinetic energy changes are negligible Fluid is flowing in one direction inside each tube All fluids enter the heat exchanger with uniform velocity Analytical 'Forced' Errors When calculating the pressure loss coefficients in the analysis of the fin designs only two graphs were available to extract data, these are shown in appendices 9-10.

consist of
verb
Almost always used with the preposition "of," the verb consist means to be made up of, or composed of something. A heated conversation might consist of only two words: "yes" and "no." If you're talking about something that is made up of other things, consist is your word. A molecule consists of atoms and their bonds.
Example: The crosses were cut on three of the stones and CONSIST OF two well - formed Chi - Rho symbols and four simple crosses

Convection
noun
Convection is defined as the heat transmitted in a liquid or gas as a consequence of the actual movement of the heated particles within it. If this movement is due to the effect of gravitation, due to differences in density, it is called natural convection.
Example: Heat transfer from a solid to air is by conduction and partial CONVECTION.

Deal with
phrase
to be about (something) : to have (something) as a subject
Example: Adaptive structures in contrast can DEAL WITH multiple loading conditions and unanticipated events at the same time.

Fixed mass
phrase
It is a physical magnitude and general property of matter1 that expresses the inertia or resistance to change of motion of a body. More precisely, it is the property of a body that determines its acceleration, when it is under the influence of a given force.
Example: On palpation a small FIXED MASS was detected, approximately 1.5cm in size

Heat transfer
noun
Heat transfer, any or all of several kinds of phenomena, considered as mechanisms, that convey energy and entropy from one location to another. The specific mechanisms are usually referred to as convection, thermal radiation, and conduction (see thermal conduction).
Example: Anytime the HEAT TRANSFER coefficient is increased in these components, there is a corresponding increase in frictional pressure drop; therefore, a delicate balance is required between these two effects in heat exchanger optimization.

inner surface
noun
Example: Upon the INNER SURFACE of the envelope, Matrix protein or M1 coats the entire surface, stabilising the particle structure.

Internal energy
phrase
The internal energy of a thermodynamic system is the energy contained within it. It is the energy necessary to create or prepare the system in any given internal state.The thermodynamic processes that define the internal energy are transfers of matter, or of energy as heat, and thermodynamic work.
Example: The INTERNAL ENERGY of an ideal gas depends on temperature only and is independent of pressure or volume.
en: Energía interna
mass transfer
phrase
Mass transfer is the net movement of mass from one location to another or travel of individual chemical species from high-concentration regions to low-concentration regions.
Example: Issues can arise with agitation, heat or MASS TRANSFER and isolation when scaled larger, which are all key to manufacture
en: transferencia de masa
open system
phrase
An open system is a system that has external interactions.An open system is contrasted with the concept of an isolated system that does not exchange energy, matter or information with its environment. An open system is also known as a flow system.
Example: After another 10 per cent of the sentence is served in the OPEN SYSTEM of Stage 4, the prisoner is placed on probation and allowed to go home
en: sistema abierto
outer surface
noun
The outside part or uppermost layer of something
Example: However he noted that his category of wide - mouthed cook - pots are often smoke - blackened on the OUTER SURFACE.

Radiation
noun
Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”
Example: Every atom seeks equilibrium at the lowest energy level, giving off surplus energy as RADIATION.
en: Radiación
total energy
phrase
The total energy of a system is the sum of kinetic and gravitational potential energy, and this total energy is conserved in orbital motion. ... Objects with total energy less than zero are bound; those with zero or greater are unbounded
Example: In terms of TOTAL ENERGY intensities, the electronic industry is more energy-intensive than the national average. The other service industries, although they are less energy-intensive than the national average in terms of both direct energy input and TOTAL ENERGY requirements, did not help much in reducing national energy intensity.
en: energía total
undergo
verb
experience or be subjected to (something, typically something unpleasant, painful, or arduous).
Example: It is only through the influence of individuals who can set an example, and whom the masses recognize as their leaders, that they can be induced to perform the work and UNDERGO the renunciations on which the existence of civilization depends.
