What is the meaning of rapid diffusion?
1The spreading of something more widely. ‘the rapid diffusion of ideas and technology’ ‘Through these, new subject matter and models were widely disseminated, with diffusion into book illumination and sculpture.
What is the best definition of diffusion?
1 : the act of spreading or allowing to spread freely. 2 : the mixing of particles of liquids or gases so that they move from a region of high concentration to one of lower concentration.
What part of speech is diffusion?
the act of diffusing or dispersing something, or the property of being diffused or dispersed; dispersion. the scattering of light by reflection from a rough surface, or by passage through a translucent medium. the intermingling of the molecules of a fluid due to random thermal agitation.
What is technology diffusion definition?
Technology diffusion can be defined as the process by which innovations are adopted by a population.
What is diffusion Class 9?
The process of movement of a substance (solid, liquid, or gas) from the region of higher concentration to the region of lower concentration so as to spread uniformly is called diffusion.
What type of diffusion is technology?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place. This kind of proliferation is known as spatial diffusion.
Why is technology diffusion?
The importance of new technologies derives from the fact that they spread across many different users and uses, as well as different geographic regions. The diffusion of technological improvements, across producers within a country and across international borders, is critical for long run growth.
What is diffusion give two examples?
A tea bag immersed in a cup of hot water will diffuse into the water and change its colour. A spray of perfume or room freshener will get diffused into the air by which we can sense the odour. Sugar gets dissolved evenly and sweetens the water without having to stir it.
What is diffusion class 12th?
Diffusion is the process where gaseous atoms and molecules are moved from regions of comparatively high concentration to regions of comparatively low concentration. Diffusion of gas is inversely proportional to the molecular weight of the gases.
What is an example of diffusion in animals?
Example of diffusion in an animal cell The cells in our body need glucose and oxygen for respiration. Both these are carried in the blood. When blood reaches the cells the molecules of glucose and oxygen diffuse out of the blood and into the cells.
Is mobile phone a technology?
Mobile technology is technology that goes where the user goes. It consists of portable two-way communications devices, computing devices and the networking technology that connects them. Currently, mobile technology is typified by internet-enabled devices like smartphones, tablets and watches.
What is diffusion explain with an example?
diffusion, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. A familiar example is the perfume of a flower that quickly permeates the still air of a room.
What is the simple diffusion of water called?
The simple diffusion of water is known as osmosis. It has a separate name to distinguish when water travels without its solutes, as in the case of water traveling through the cell membrane. The solutes originally distributed in the water are left behind, as the water rushes to balance the concentration of solutes within the cell.
What is the difference between simple diffusion and active transport?
Unlike in simple diffusion, molecules can be moved against their gradient using active transport systems. Simple diffusion is present in a number of biological systems, including the delivery of oxygen, water, and other small molecules to the cells of the body.
What is the material that diffuses?
The material that diffuses could be a solid, liquid or gas. Similarly, the medium in which diffusion occurs could also be in one of the three physical states. One of the main characteristics of diffusion is the movement of molecules along the concentration gradient.
