Question

1. What is diffusion? Which diffuse most, a solid or a gas? Why?
​

Answer 1

Answer:

diffusion is a net movement of anything from a region higher concentration to a region of lower concentration

gas diffuses fastly

1. because there is large space between the particles of gas
2. gas particles moves speedily

Hlw dude !!

$\bf\bigstar{QUESTION}$

What is diffusion? Which diffuse most, a solid or a gas? Why?

$\bf\bigstar{ANSWER}$

$\bf\green\star\underline{Diffussion}$

Diffusion is defined as the movement of atoms, ions, and molecules from a region of high concentration to a region of low concentration, or ‘down their concentration gradient’. The word ‘diffusion’ is derived from the Latin word, ‘diffundere’, meaning ‘to spread out’.It is a fast and spontaneous process . When occurring across a biological membrane, it is a type of passive transport . Requires no energy expenditure

$\bf\green\star\underline{Examples}$

☆ The spreading of the odor of a scent or a perfume from the region applied to a nearby region .

☆ Dissolving ice, sugar, salt crystals in water to form a uniform solution.

GASES DIFFUSES MORE THAN SOLIDS.

Reason :

The movement of molecules in solids is very small, relatively large in liquids and very large in gases. And this movement of molecules has to lead to a phenomenon called as diffusion. It happens faster if the temperature is increased.

Hope this answer can helps u dear !!
