Diffusion and Temperature: Water & Pen ink & Vinegar

Pen ink consists of several ingredients. One of them is a dye which imparts color to the ink. When we add a drop of ink into the cold water, the ink is mixed with it by means of diffusion - dispersion of particles of ink ingredients in the water. The warm water diffusion occurs faster because the particles have more energy, and the spaces between them are larger (more easily with each other squeeze).

My Mom when she sees it,
HEY! You are dirtying the glasses, 😠😠😠!
Me : No, I
Me : 💀

What would happend if we pour vineger int that cold H2O???? 🤔

[marcopaulocorpuz]

Why did the vinegar made the ink on the hot water visible? What happened? I need in on my experiment pleaaseee.

Great video! Shows that high T causes higher diffusion coefficients, and clearly demonstrates that convection dominates at low-T (low D_ab) and diffusion is more dominant at high-T (high D_ab). TYVM!

I did this and it worked with ink pen too

Did the addition of vinegar cause the cations to be flushed out from the gaps between water molecules?

[AdnanAli-eyby]

Hey does it remain the same even after the hot water cools down ???

[blckjck]

do all weak acids work as an alternative for vinegar?

[rinu]

May I know why you added vinegar to the hot water?

კარგი ექსპერიმენტებია, მომწონს, ხშირად ვატარებთ ჩვენც, ასე უფრო აცნობიერებენ სხვადასხვა მოვლენას.

What if you dont have that kind of ink

[bindhu]

what ink are you using ? I tried with marker pen ink tube..it didn't work

[unnatitrivedi]

i can't understand what is this activity shows

This isn't diffusion because it deals with water it is osmosis.
