Vivek said: (Oct 12, 2010)  
Blotting paper provide a capillary tube for ink so ink fill in capillary tube and absorbed by blotting paper continuously.

Tapash said: (Jul 25, 2011)  
I think it should be diffusion of ink through the blotting.

Mounica said: (Aug 11, 2011)  
I surely think that diffusion of ink through blotting paper due to the phenomena of diffusion.

HARSHITA said: (Oct 8, 2011)  
It is diffusion of ink through the blotting.

Ajay said: (Jan 12, 2012)  
Transfer of liquid from high concentration to low concentration. Ex: plants absorb water from ground by this phenomenon.

000 said: (Jan 23, 2012)  
I think it is the capillary phenomenon.

Chandru said: (Feb 1, 2012)  
Why it is not diffusion phenomenon?

Anu said: (May 9, 2012)  
Capillary action, or capillarity, is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to external forces like gravity. The effect can be seen in the drawing up of liquids between the hairs of a paint-brush, in a thin tube, in porous materials such as paper, in some non-porous materials such as liquified carbon fiber, or in a cell. It occurs because of inter-molecular attractive forces between the liquid and solid surrounding surfaces. If the diameter of the tube is sufficiently small, then the combination of surface tension

Rajkamal Gupta said: (Jun 29, 2012)  
Blotting paper is thick soft paper that you use for soaking up and drying ink on a piece of paper. So It has many capillarity tube by which ink may be absorb in piece of paper.

Ajeet said: (Dec 5, 2012)  
Blotting paper consist of tiny capillaries and due to cohesion and adhesin forces the ink rises up.

Babita Gupta said: (Apr 7, 2013)  
I also sure that it is due to capillary tube so continuosly ink flow through thin tube.

M.zee said: (May 27, 2013)  
What is a capillary action phenomenon?

Naina said: (May 29, 2013)  
What is capillary action?

Clinks said: (Jul 29, 2013)  
I'm sure its diffusion, diffusion is the process in which a higher solute concentration moves to a lower solute concentration.

Sahil said: (Sep 9, 2013)  
Capillary action is due to surface tension of liquid, when a capillary is submerged in a liquid, the liquid will rise or fall due its surface tension and pressure.

GAUTAM said: (Sep 20, 2013)  
What is diffusion of ink?

Debashish said: (Oct 11, 2013)  
It is capillary of ink through pen.

Savera said: (Oct 18, 2013)  
Capillary action is the ability of liquid to flow in narrow space.

Ashutosh said: (Jan 24, 2014)  
What is capillary action?

Bhavana said: (Jan 25, 2014)  
I think the absorption of ink by blotting paper involves capillary action phenomenon because the blotting paper is a thin and a smooth paper which allows a little thicker liquids like ink to absorb.

Nibedita said: (Feb 19, 2014)  
The phenomenon of rise or fall of liquid in a capillary tube is capillarity. As fine pores of blotting paper act like capillary tubes ink rises in them.

Mahendiran said: (May 6, 2014)  
Ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity.

Prasanta Saha said: (Jun 8, 2014)  
What is the meaning of blotting paper?

Junaid said: (Jun 10, 2014)  
It is a paper which absorb liquid like tissue paper. And the correct answer is diffusion of ink through the blotting paper.

RAJA said: (Jul 22, 2014)  
Diffusion refers to the movement of liquid between different concentrations but this is not actually that her pores in the blotting paper absorbs the neglecting the forces of gravity so here the capillarity action is done.

Suba said: (Aug 4, 2014)  
What is capillary action phenomenon how this used in absorption method?

Raja Kumar said: (Aug 23, 2014)  
Conjugation of my thought it may diffusion of ink through blotting paper am I right or wrong.

Paschal Rog said: (Sep 21, 2014)  
How can blotting paper absorbs ink?

Emmanuel said: (Sep 30, 2014)  
Blotting paper absorb ink through capillary action. Thus B is the correct answer.

Saket Laura said: (Oct 13, 2014)  
What is blotting ink paper?

Y.dileep Kumar said: (Oct 25, 2014)  
What is capillary action phenomenon? I want a explanation. Please tell me.

Haleemah said: (Nov 11, 2014)  
Capillary is the rising up of liquid in a tube.

Vinayak said: (Dec 1, 2014)  
Its because of capillary action.

Ousman said: (Dec 14, 2014)  
I really love this question and answer online because it really make physics and easy and interesting subject. So there I really thank you for your wonderful affords to wards this subject.

Thank you.

Chidex said: (Jun 14, 2015)  
It is cause due to capillary action as, I t tends to rise adhesive force is involve, as it falls cohesive force is involve.

Chidex said: (Jun 14, 2015)  
It is cause due to capillary action as, It tends to rise adhesive force is involve, as it falls cohesive force is involve.

Mwamba Abraham said: (Aug 22, 2015)  
I strongly think that its through capillary action.

SUNIL KUMAR said: (Sep 22, 2015)  
I think it is by capillary action.

Prasant Pradhan said: (Oct 13, 2015)  
I think the capillary tube action it.

Subrat Kumar said: (Apr 12, 2016)  
I think absorption is due to the force act in the paper.

Brian said: (Jun 8, 2016)  
Guys I have met with the same problem. This question was asked one of my entrance exams I have selected B option.

But when I saw in my book it was option A, So I confused with this can anybody tell the correct option?

Mateen Murad said: (Aug 7, 2016)  
What is siphon action?

Ajith said: (Oct 17, 2016)  
Please explain its process.

Hsu Pyae Sone said: (Oct 22, 2016)  
Can anyone explain me about this process?

Ishaq said: (Dec 4, 2016)  
I think it is the capillary phenomenon.

Waheed Kaka Khel said: (Dec 21, 2016)  

The diffusion will be there it true then there must be a gape between the particle to allow for diffusion the ink so the answer should be b because the capillary tube will allow the dopping material to fill the blanks that are the basic reason.

Pankak Gupta said: (Dec 23, 2016)  
I think blotting paper involve by ink capillary action.

Sourabh Kumar said: (Jan 13, 2017)  
Due to the capillary action.

Abduljabbar Shouqi said: (Jan 21, 2017)  
I think D is the answer.

Jason said: (Apr 20, 2017)  
Viscosity of ink is the correct answer.

John. said: (May 14, 2017)  
It's due to capillary action. A blotting paper has some porous holes in it.

Iremide said: (May 24, 2017)  
What is the action of blotting paper on ink due to?

Satya said: (Jul 20, 2017)  
It is due to cohesive and adhesive force.

Cele said: (Dec 3, 2017)  
Actually it is diffusion.

EMMAH said: (May 13, 2018)  
Surely, it seems to be diffusion since on the paper the ink was highly spread in one position and at last absorbed to low concentrated region.

Nazlin said: (Jul 8, 2018)  
What is the reason for sweet can be blotted with tissue paper?

Dnyaniya Gurav said: (Oct 12, 2019)  
It is due to adhesive force.

Otonashi-san said: (Jun 11, 2020)  
Why isn't it diffusion?

Brains said: (Sep 23, 2021)  
A blotting paper absorbs ink through the phenomena of diffusion.

Damie said: (Aug 6, 2022)  
Why it is not diffusion? Explain, please.
