Writing with a pen involves a physical change rather than a chemical change. A chemical change involves the formation of new substances with different chemical properties, while in writing with a pen, the ink is simply transferred onto the paper without any chemical reactions occurring. The ink may undergo physical changes such as drying or adhering to the paper, but the chemical composition of the ink remains the same.

No, writing with a pen is a physical change. The ink from the pen is simply being transferred to paper without any chemical reactions occurring.
Yes, the drying of fountain pen ink is a physical change rather than a chemical change. The ink dries through evaporation of the solvent, leaving behind the solute (pigments or dyes), which does not undergo a chemical reaction during the drying process.
Your pen may stop writing due to a clog in the ink flow, a dried-out ink cartridge, or a damaged pen tip.
physical change. You know that it is a physical change because it can be reversed. An example of a chemical change would be cooking an egg. Because you cannot reverse the process.
Spectator ions do not change in a chemical reaction as they appear in the reactants and products in the same ionic form. They do not participate in the reaction and are typically omitted when writing net ionic equations.
Chemical change. References: Intro to Matter book.
Yes, burning a pen is a chemical change because it involves a rearrangement of the atoms in the pen due to the combustion process. New substances are formed during the burning, such as ash and smoke, which are different from the original materials in the pen.
It is a physical change because it is still fountain pen ink. It wouldn't be a chemical change because it didn't change into a new substance.
Writing out a chemical equation for a specific chemical reaction.
Physical change
Yes, the drying of fountain pen ink is a physical change rather than a chemical change. The ink dries through evaporation of the solvent, leaving behind the solute (pigments or dyes), which does not undergo a chemical reaction during the drying process.
some pens such as calligraphy pens make writing look better, but the pen generally can't change your handwriting
It is a physical process.

Two homonyms for "pen" are "pen" as in the tool used for writing and "pen" as in an enclosure for animals.
Your pen may stop writing due to a clog in the ink flow, a dried-out ink cartridge, or a damaged pen tip.
