15 Reading Comprehension- Heat Transfer Summary terms
closed system
Noun
A closed system is a physical system that does not allow transfer of matter in or out of the system, though, in different contexts, such as physics, chemistry or engineering, the transfer of energy is or is not allowed.
Example: the contents of a pressure cooker on a stove with its lid tightly closed and the whistle in position, is a closed system as no mass can enter or leave the pressure cooker, but heat can be transferred to it.
es: sistema cerrado
Conduction
Noun
transmission through or by means of a conductor also
Example: Heat transfers into your hands as you hold a hot cup of coffee.s
es: Conducción
consist of
verb
to be formed or made up of
Example: Their lives consist of the humdrum activities of everyday existence
es: Consiste de
Convection
Noun
Convection is the transfer of heat by circulating it through air or liquids
Example: Heat transfers as the barista “steams” cold milk to make hot cocoa
es: Convección
Deal with
Verb
to take appropriate action in a particular situation or according to the person you are talking
Example: to make business agreements with
es: Tratar con
Fixed mass
Noun
It is when no mass can enter or leave a closed system
Example: Closed system
es: Masa fija
Heat Transfer
Noun
is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy (heat) between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes.
Example: Heat transfers into your hands as you hold a hot cup of coffee
es: Transferencia de calor
inner surface
noun
the environment beneath the surface of the sea
Example: the environment beneath the surface of the sea
es: Superficie interior
Internal energy
Noun
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
Example: A very simple example of this can be a glass of water at room temperature which is kept on a shelf or table
es: Energía interna
mass transfer
Noun
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. Mass transfer is used by different scientific disciplines for different processes and mechanisms.
Example: the evaporation of water from a pond to the atmosphere
es: Transferencia de masa
open system
Noun
An open system can exchange both energy and matter with its surroundings
Example: when you are boiling soup in an open saucepan on a stove, energy and matter are being transferred to the surroundings through steam.
es: sistema abierto
outer surface
noun
The outside part or uppermost layer of something
Example: Athree-dimensional model of serial cross sections of the coronary arteries shows the inner surface three-dimensionally through the outer surface.
es: Superficie exterior
Radiation
Noun
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Example: Reheating a cold cup of coffee in a microwave oven
es: Radiación
Total energy
Noun
Total energy is the sum of all different types of energies a body can have.
Example: The total energy of an electron in an atom in an orbit is -3.4 eV.
es: Energía total
undergo
adjectiv
A system undergoes a thermodynamic process when there is some energetic change within the system that is associated with changes in pressure, volume and internal energy.
Example: the burning gasoline inside the cylinder of the engine
