This glossary is for the class of heat transfer, and it´s designated to be the homework for the reading comprehension for this week.
closed system
phrase
is a type of thermodynamic system where mass is conserved within the boundaries of the system, but energy is allowed to freely enter or exit the system.
Example: By contrast, a CLOSED SYSTEM of general values with a well-ordered hierarchy of values for Weber is impossible.

conduction
noun
The process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
Example: Heat transfer by CONDUCTION in the gas becomes negligible compared with heat transfer through convection.
en: conducción
consist of
verb
to be made of or formed from something:
Example: However, most banks tend to use only the most basic of statistical analyses to develop these guidelines, meaning that in most cases the rule sets CONSIST OF a set of simple threshold conditions on account variables.

convection
noun
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
Example: He decay of radioactive isotopes in the mantle is constantly producing heat which goes into powering the solid state CONVECTION cycle associated with plate tectonics.

Deal with
phrase
When you deal with something or someone that needs attention, you give your attention to them, and often solve a problem or make a decision concerning them.
Example: Hence, it may be more efficient to negotiate the topics regarding FDI, such as new rules that DEAL WITH investment, copyright law, and the harmonisation of health and safety regulations, on the multilateral level (Josling, 1993).

emissivity
noun
the relative power of a surface to emit heat by radiation : the ratio of the radiant energy emitted by a surface to that emitted by a blackbody at the same temperature
Example: the emissivity help us to find if someone has high temperature due to covid 19
en: emisividad
fixed mass
phrase
that means that the mass will be the same in all the process
Example: of the photon is the fixed mass of an elementary particle.
en: masa fija
Heat transfer
phrase
The movement of heat across the border of the system due to a difference in temperature between the system and its surroundings.
Example: On the surface deposits of materials can accumulate that reduce the HEAT TRANSFER and increase the pressure drop.

inner surface
noun
The inner parts of something are the parts which are contained or are enclosed inside the other parts, and which are closest to the centre.
Example: Upon the INNER SURFACE of the envelope, Matrix protein or M1 coats the entire surface, stabilising the particle structure.
en: superficie interna
internal energy
phrase
is defined as the energy associated with the random, disordered motion of molecules. It is separated in scale from the macroscopic ordered energy associated with moving objects
Example: Theory 2.1 The INTERNAL ENERGY of an ideal gas The addition of heat results in an increase in a substances internal molecular energy.

mass transfer
phrase
Mass transfer is the net movement of mass from one location, usually meaning stream, phase, fraction or component, to another. Mass transfer occurs in many processes, such as absorption, evaporation, drying, precipitation, membrane filtration, and distillation.
Example: Movement of air across the crop allows for greater energy and MASS TRANSFER, mixing air from the mass of the atmosphere with the relatively still air directly around the plant.
en: transferencia de masa
open system
phrase
a material system in which mass or energy can be lost to or gained from the environment.
Example: Realism solves this problem as it recognises that society is an OPEN SYSTEM in which events are influenced by other contingencies, so the causal influence of emergent properties is not to consistently produce observable effects
en: sistema abierto
outer surface
noun
The outside part or uppermost layer of something
Example: The Biochemistry Of PhotosynthesisLight- Dependent Reaction (Fig 3): In both C 3 and C 4 plants, the chlorophyll molecules are arranged in the membranes of the thylakoids so that the haem group projects from the OUTER SURFACE.
en: Superficie exterior
quantity
noun
the amount or number of a material or immaterial thing not usually estimated by spatial measurement.
Example: The formula means the percentage change in QUANTITY that takes place when price changes by one percent.
en: cantidad
radiation
noun
Radiation heat transfer is the energy that is emitted by matter in the form of photons or electromagnetic waves. Radiation can be important even in situations in which there is an intervening medium.
Example: An example is the heat transfer that take place between a living entity with its surrounding.
en: radiación
total energy
phrase
Total energy is the sum of all different types of energies a body can have.
A body usually has 2 types, kinetic energy and potential energy. Total energy= K.E+P.E
Example: The dietary intakes of these nutrients are expressed as percentage of daily TOTAL ENERGY intake and so it is hard to judge whether students' daily intakes are optimum.
en: energía total
undergo
verb
to experience something that is unpleasant or something that involves a change
Example: I had to undergo a medical examination when I started my pension scheme.
