What does lingua franca literally mean?
In Lingua Franca (the specific language), lingua means a language, as in Italian, and franca is related to phrankoi in Greek and faranji in Arabic as well as the equivalent Italian. In all three cases, the literal sense is “Frankish”, leading to the direct translation: “language of the Franks”.
What does lingua franca mean in English?
1 often capitalized : a common language consisting of Italian mixed with French, Spanish, Greek, and Arabic that was formerly spoken in Mediterranean ports. 2 : any of various languages used as common or commercial tongues among peoples of diverse speech English is used as a lingua franca among many airline pilots.
What is the lingua franca of the world?
English
What is a lingua franca quizlet?
Lingua Franca. Definition: A language mutually understood and commonly used in trade by people who have different native languages.
What is an example of a lingua franca?
The most obvious modern example is English, which is the current dominant lingua franca of international diplomacy, business, science, technology and aviation, but many other languages serve, or have served at different historical periods, as lingua francas in particular regions, countries, or in special contexts.
How has expansion diffusion occurred with English give three examples?
How has expansion diffusion occurred with English? Give three examples. Ebonics, Spanglish, text using the vocabulary, spelling and pronunciation, English words fusing with other languages. Others feel the English is being forced upon them.
What are the two ways that expansion diffusion has occurred with English?
How has expansion diffusion occurred w/ English? English has spread through the snowballing effect of an idea rather than through the relocation of people. English is changing through the diffusion of new vocabulary, spelling, and pronunciation. English is also fusing w/ other languages.
What is the basis of diffusion?
Diffusion is driven by a gradient in concentration. The word diffusion derives from the Latin word, diffundere, which means “to spread out.” A distinguishing feature of diffusion is that it depends on particle random walk, and results in mixing or mass transport without requiring directed bulk motion.
What is osmosis vs diffusion?
Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
What is called diffusion?
Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells.
What is the rate of diffusion in liquid?
The rate of diffusion of liquids is higher than that of solids. This is due to the fact that in the liquid state, particles move freely and have greater space between each other as compared to particles in the solid state.
What 4 factors affect the rate of diffusion?
The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure. Diffusion takes place as long as there is a difference between the concentrations of a substance across a barrier.
Why the rate of diffusion is faster in liquid than solid?
Already we know that the molecules will be able to move only if they have free space available. In solids the molecules are very tightly packed. If we consider the molecules of liquid, the molecules are loosely packed compared to the solids. Therefore, the rate of diffusion in liquids will be faster than the solids.
Why the rate of diffusion in liquid is higher than solid?
Complete answer: Solids have tightly packed crystal lattices. In solid, the particles are very close to each other and the interparticle space is very small. Due to this, the rate of diffusion of liquids is higher than that of solids as liquids have higher inter-particle space than solids.
In which case rate of diffusion is highest?
Rate of diffusion is faster in gas because inter molecular attraction is comparatively less in gases.So they are very free to move as compared to solid materials.
Which state of matter has the strongest intermolecular forces the weakest?
Solids have the strongest intramolecular forces.
Why do solids do not show diffusion?
For diffusion to work, the particles must be able to move around. This means that diffusion does not happen in solids – the particles in a solid can only vibrate and cannot move from place to place.
How is the movement of particles in diffusion determined?
Diffusion is the movement of particles move from an area of high concentration to an area of low concentration until equilibrium is reached. The rate of this movement is a function of temperature, viscosity of the fluid and the size (mass) of the particles.
Is diffusion faster gas or liquid?
The distance between the constituent particles in gases becomes greater than in liquids, resulting in diffusion faster in gases than in liquids. Therefore, gas particles have higher kinetic energy and travel more rapidly. Therefore, diffusion of gases is much quicker than liquid diffusion.
What does not affect the rate of diffusion?
The amount of energy available for transport molecules does not affect the rate of diffusion. This is because diffusion is a passive process.
Does pH affect diffusion?
Diffusion coefficients were determined by means of numerical solutions of Fick’s laws with appropriate boundary conditions. It has been found that the pH of the medium strongly influences diffusion.
How does size affect the rate of diffusion?
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared. When there is more volume and less surface area, diffusion takes longer and is less effective.
