1. in your PDF book ¨Heat Transfer a practical approach ¨, Read the summary of chapter one, on page 46 (or 66 of the document)
2. Create an electronic glossary with vocabulary and key concepts from the reading to get familiar with terminology.
Absorptivity
Noun
The property of a body that determines the fraction of incident radiation absorbed by the body.
Example: The passage from liquid water to vapor represents an absorptivity of heat that is released when this vapor, as it rises and cools, condenses to form clouds.
es: Absorción
Boundaries
Noun
A line that marks the limits of an area; a dividing line.
Example: SOCIAL BOUNDARIES AND LIMINALITY The function of brochs need not be restricted to a purely utilitarian or functionalist interpretation.
es: Límites
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: Early theorists assumed a business to be a CLOSED SYSTEM, and hence, focused on the inner arrangements of a business such as altering policies and working incentives for employees.
es: Sistema cerrado
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: Thick products which heat by CONDUCTION, and whose thermal diffusivities are about the same as water, there being insufficient or no covering liquid.
es: Conducción
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: To conserve heat loss by radiation, CONVECTION and conduction blood flow to the dermis of the skin is reduced.
es: Convección
Fixed
Adjetive
fastened securely in position.
Example: Today all the rates collected go to the national pool and the Government re-distributes this money to local councils on a FIXED amount per head which differs for each class of authority such as district council, county council, police authority or unitary authority
es: Reparada o Reparado.
Fixed mass
Noun
We concluded that the company couldn't be profitable because its small critical mass could not absorb fixed costs. Additionally, they had a weak executive team.
Example: On palpation a small FIXED MASS was detected, approximately 1.5cm in size.
es: Masa fija
kinetic
Adjective
Relating to the motion of material bodies and the forces and energy associated.
Example: The kinetic energy of moving water is transformed into electrical energy.
es: cinética o cinético
Radiation
Noun
The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
Example: There were empty niches for specialisation as seed eaters, cactus eaters etc. and eventually became distinct species as observable today (adaptive RADIATION ). 16) Competitive Exclusion The supposed principle of ecology, competitive exclusion states that two species with very similar adaptations cannot coexist in the same ecological niche.
es: Radiación
Surface
Noun
To the extension or area of a territory
Example: There are signs of use on the leather housing on the sides in the places where chain would have contacted with its SURFACE.
