⭐⭐ Filling of ink into a FOUNTAIN pen ⭐⭐

➡ As a syringe is filled with a liquid due to the atmospheric pressure, ink ALSO gets filled in a fountain pen. Actually, when the rubber tube of fountain pen is pressed, almost all the air of rubber tube EXPELS out in the form of bubbles through the ink.

➡ When the rubber tube is released, the pressure inside the rubber tube is much LESS than the atmospheric pressure acting on the ink. As a RESULT, the ink rises into the tube through the capillary below the nib if the pen.

✨ ICSE WILL LOOK INTO YOUR KEYWORDS.

✨ KEYWORDS ARE :- Syringe, atmospheric pressure, nib, rubber tube (inside the ink), capillary below the nib, pressure on the ink and nib.

✨✨✨✨ ALWAYS BE BRAINLY ✨✨✨✨
