The glossary contains vocabulary and key concepts from the summary of Chapter 1 of the book 'Heat Transfer a practical approach' to get familiar with the terminology.
Absence
Noun.
The fact of somebody being away from a place where they are usually expected to be.
Example: She has had repeated absences from work this year.
en: Ausencia.
Absorptivity
Noun.
The property of a body that determines the fraction of incident radiation absorbed by the body.
Example: These features provide absorptivity increase and high filtering efficiency.
en: Absortividad.
Adjacent
Adjective.
Next to or adjoining something else.
Example: They work in adjacent buildings.
en: Adyacente.
Approach
Verb.
Come near or nearer to (someone or something) in distance or time.
Example: The train approached the main line.
en: Enfoque. / Acercarse.
Closed system
Noun.
A region that is isolated from its surroundings by a boundary that admits no transfer of matter or energy across it.
Example: To the extent that a closed system is completely isolated from external factors, its end states are determined by initial conditions.
en: Sistema cerrado.
Conduction
Noun.
The process by which heat or electricity goes through a substance.
Example: His most important work was concerned with the conduction of heat and with spectroscopy.
en: Conducción.
Consist of
Phrasal verb.
To be formed from the people or things mentioned.
Example: It's a simple dish to prepare, consisting mainly of rice and vegetables.
en: Consistir de algo.
Convection
Noun.
The transmission of heat in a fluid or gas by the circulation of currents.
Example: The final transfer of energy to the surface is by convection.
en: Convección.
Deal with
Phrasal verb.
To take appropriate action in a particular situation or according to the person you are talking to, managing, etc.
Example: She's used to dealing with difficult customers.
en: Tratar con. / Encargarse de algo.
Emissivity
Noun.
The relative power of a surface to emit heat by radiation.
Example: The amount of thermal radiation depends on the emissivity of the object.
en: Emisividad.
Enclosed
Adjective.
Surrounded or closed off on all sides.
Example: The houses on this street have enclosed gardens.
en: Cerrado.
Fixed mass
Noun.
Amount of matter that is stable or permanent and is not exposed to change or alteration.
Example: Where the final solvent volume is not measured directly, a fixed mass of internal standard should be added to enable measurement of the volume.
en: Masa fija.
Flux
Noun.
The action or process of flowing or flowing out.
Example: The flux of electrons between the two electrodes is constant.
en: Flujo.
Heat transfer
Noun.
The transfer of energy from one body or system to another as a result of a difference in temperature. The heat is transferred by conduction, convection, and radiation.
Example: The convection enhances the heat transfer from the melt and alters the rate of solidification.
en: Transferencia de calor.
Inner surface
Noun.
Inside the top layer of something.
Example: According to this conception there is a thin layer of void between the water and the inner surface of the container.
en: Superficie interna.
Internal energy
Noun.
The total amount of energy in a system, equal to the kinetic energy added to the potential energy.
Example: The internal energy of the plasma is distributed in its thermal and ionization energy.
en: Energía interna.
Kinetic energy
Noun.
Energy that an object or system has because it is moving.
Example: The energy of disturbances is primarily kinetic energy.
en: Energía cinética.
Latent heat
Noun.
The energy released or absorbed that changes the state of a body during a constant temperature process.
Example: During evaporation a molecule of water absorbs latent heat.
en: Calor latente.
Mass transfer
Noun.
Amount of matter moved from one place to another.
Example: The contact between the boiling particles and hot air helps facilitate heat and mass transfer.
en: Transferencia de masa.
Negligible
Adjective.
So small or unimportant as to be not worth considering.
Example: The difference between the two products is negligible.
en: Despreciable. / Insignificante.
Open system
Noun.
A region separated from its surroundings by a boundary that admits a transfer of matter or energy across it.
Example: An open system can exchange both energy and matter with its surroundings.
en: Sistema abierto.
Outer surface
Noun.
The outside part or uppermost layer of something.
Example: We apply a special treatment to the tube's outer surface depending on the application.
en: Superficie externa.
Potential energy
Noun.
The form of energy that an object gains as it is lifted.
Example: Spring forces contain a history list describing the origins of the potential energy.
en: Energía potencial.
Radiation
Noun.
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Example: Residents argued that electromagnetic radiation emitted by the radar towers might pose a health hazard.
en: Radiación.
Sensible heat
Noun.
The energy is transferred as heat to an object, changing the temperature but not its state. You can measure the temperature of the heat.
Example: The solar radiation incident on urban surfaces is absorbed and then transformed to sensible heat.
en: Calor sensible.
Temperature gradient
Noun.
The rate of change of temperature with displacement in a given direction.
Example: The temperature gradient mechanism is mainly used to produce precise small bend angles in thick sheets.
en: Gradiente térmico.
Thickness
Noun.
The distance between opposite sides of something.
Example: Just feel the thickness of this carpet!
en: Espesor.
Total energy
Noun.
The sum of all forms of energy of a system. It includes the internal, kinetic, and potential energies.
Example: The first law asserts that if heat is recognized as a form of energy, then the total energy of a system plus its surroundings are conserved.
en: Energía total.
Undergo
Verb.
To experience something that is unpleasant or something that involves a change.
Example: Playing board games is undergoing a revival in popularity.
en: Recibir. / Experimentar.
Whereas
Conjunction.
Used to compare or contrast two facts.
Example: He must be about 60, whereas his wife looks about 30.
