what is diffusion explain
Answers
Common Examples of Diffusion. You can smell perfume because it diffuses into the air and makes its way into your nose. A teabag placed in a cup of hot water will diffuse into the water. Placing food coloring in a liquid will diffuse the color.
Diffusion pertains to the spontaneous net movement of particles down their concentration gradient (i.e. difference in the concentrations of substances or molecules between two areas). ... For instance, polar molecules diffuse across a cell membrane through carrier molecules embedded in the cell membrane.
The phenomenon of diffusion of one substance into another substance goes on until a uniform mixture of the substance is formed. Let us explain the phenomenon of diffusion with an example. Take a glass jar full of chlorine gas and invert another glass jar containing air over it. What do you think will happen after sometime? After sometime, you will observe that the greenish yellow gas of chlorine has spread into the upper glass jar containing air. Thus, the upper glass jar which contains colourless air turns greenish yellow. This is due to the diffusion of chlorine gas in air. The rate of diffusion increases with increase in the temperature of the substance. This is because when the temperature of a substance is increased by heating, the particles present in it gains kinetic energy and moves faster which increases the rate of diffusion (Fig.).
