Question

Объясните, на каком явлении основано письмо на бумаге.​

Answer 1

Ответ:

1) Абсорбция (впитывание)

2) смачиваемость поверхности (капля расплывается, а не сворачивается, как ртуть

3) поаерхностное натяжение и капилярность

На вощенной бумаге чернила сворачиваются почти как ртуть -писать трудно - чернила сворачиваются.

НА промокашке работает 1, 2, 3 явления-чернила впитываются и расплываются

Answer 2

The Phenomenon of Writing on Paper

Writing on paper is based on the physical properties of paper and the use of writing instruments such as pens or pencils. Paper is a versatile material that has been used for centuries as a medium for writing, drawing, and printing. It is made from plant fibers, usually from wood pulp or cotton, which are processed and formed into thin sheets.

The process of writing on paper involves applying pressure to a writing instrument, such as a pen or pencil, which leaves a mark on the paper's surface. The ink or graphite from the writing instrument is transferred onto the paper, creating visible lines or marks that form letters, words, and images.

Paper as a Writing Medium Paper has several properties that make it suitable for writing:

1. Smooth Surface: Paper has a relatively smooth surface that allows for easy movement of the writing instrument, resulting in smooth and legible writing.

2. Absorbency: Paper has the ability to absorb ink or graphite, preventing smudging and ensuring that the writing remains clear and distinct.

3. Durability: Paper is a durable material that can withstand repeated handling and storage, making it a reliable medium for preserving written information over time.

4. Portability: Paper is lightweight and portable, making it convenient for writing on the go or carrying written documents.

Writing Instruments Writing on paper requires the use of writing instruments, such as pens or pencils, which leave marks on the paper's surface. Here are some commonly used writing instruments:

1. Pen: A pen uses ink to create marks on paper. There are various types of pens, including ballpoint pens, rollerball pens, fountain pens, and gel pens. Each type of pen has its own unique characteristics and writing experience.

2. Pencil: A pencil uses graphite to create marks on paper. Graphite is a soft, dark gray material that leaves a visible mark when applied to paper. Pencils are often preferred for their erasability and versatility.

3. Markers: Markers are writing instruments that use ink to create bold and vibrant marks on paper. They are commonly used for highlighting, drawing, and creating colorful designs.

Conclusion Writing on paper is a fundamental method of communication and expression. It is based on the physical properties of paper and the use of writing instruments. Paper provides a smooth and absorbent surface for writing, while writing instruments such as pens and pencils leave marks on the paper's surface. This combination of materials and techniques has allowed for the creation and preservation of written information throughout history.
