Define Brownian movement and Tyndall effect. Do dust particles in air show both these effects? Explain.
Answers
Answer:
Brownian Motion. Meaning. The phenomenon of scattering of light like a light beam that passes through a fluid (colloids) is known as the Tyndall effect. The random movement of particles in a fluid (colloids) is the Brownian motion, and it occurs due to the collisions of the particles.
Answer:
BASIS FOR COMPARISON TYNDALL EFFECT BROWNIAN MOTION
Meaning The phenomenon of scattering of light like a light beam that passes through a fluid (colloids) is known as the Tyndall effect. The random movement of particles in a fluid (colloids) is the Brownian motion, and it occurs due to the collisions of the particles.
First observed by It was first described by John Tyndall. The Botanist Robert Brown first observed it.
Property Optical Property. Kinetic Property.
Reason of Occurrence Due to the smaller size of the particles, they get scattered instead of reflecting the light. It occurs due to the unequal bombardments of the particles by the molecules of fluid.
Observation It explains the scattering of light by particles. It explains the movement of particles in a fluid.
Can be monitor by Tyndall effect can be observed by the passing a light beam through a fluid. The Brownian motion or the motion of the molecules can be observed by the use of a light microscope.
Affected By Tyndall effect can be affected by the density of particle and frequency of the light beam. Brownian motion can be affected by the factors which hinder the motion of the particle in a fluid.
Example The beam of headlights that are visible in fogs is due to the Tyndall effect. Diffusion is any fluid
Explanation:
The Tyndall effect explains the phenomenon of scattering of light by the colloidal particles in its path that results in the pattern of bright glowing cones in the fluid. The Brownian Motion is related to the phenomenon of random motion of colloidal particles in the fluid.These are the widespread phenomenon that can be observed easily, but only in colloids as these properties can not be observed in True solutions or Suspension.
True solutions are the homogenous mixture of two or more substances, Suspension is the heterogeneous mixture of components with different sizes, whereas Colloids are said as the intermediate of the suspension and true solution, as it is the heterogeneous mixtures which carry the particles with a size between 1-1000nm.
As per the language of chemistry, When two or more homogenous substances are mixed in a specific amount and can be mixed up to the certain limit of solubility are known as solutions. The term solution is not only applicable to liquids, but it covers gases and solids also.
In this post, we will be highlighting the points on which the two terms, Tyndall effect and Brownian Motion differs. We will also provide a brief description of them.
