Answer 1

Ответ:

Жив на світі Кисень. У нього не було нічого: ні справжніх друзів, ні власного будинку. Тому і жилося бідоласі дуже важко. Щоб не сумувати, він вирішив допомагати всім, хто йому в цьому потребує. Він допомагав всім живим організмам дихати, підтримував горіння брав участь у виплавці металів. Та інколи він не встигав побувати у всіх усюдах, то люди почали добувати його в лабораторіях. Кисень дуже зрадів, дізнавшись про цю новину – адже його ставало все більше і більше. Та згодом він побачив, що не по своїй волі інколи приносить не тільки користь, а й шкоду. Бо з його втручання іржавіють метали, горять речовини… Це його дуже засмутило. Щоб не заважати жителям планети Земля, він вирішив її покинути. Та раптом помітив, що позаду нього все довкола гине.

Вчасно Кисень зрозумів, що користі від нього значно більше, ніж шкоди. Він знайшов собі домівку у Періодичній системі. А коли потребують його допомоги, він тут як тут.

The Tale of Oxygen

Once upon a time, in a land far away, there was a magical element called oxygen. Oxygen was a vital part of the world, playing a crucial role in the lives of all living beings. Let me tell you the story of oxygen and its incredible journey.

Chapter 1: The Discovery of Oxygen

Long ago, in the late 18th century, a brilliant chemist named Antoine Lavoisier made a groundbreaking discovery. He found that air was not just a single substance, but a mixture of different gases. Through his experiments, Lavoisier isolated a gas that he named "oxygen," derived from the Greek words meaning "acid-former."

Chapter 2: The Breath of Life

Oxygen quickly became known as the "breath of life" because of its essential role in respiration. Every living organism, from plants to animals, relies on oxygen to survive. When we breathe in, our lungs extract oxygen from the air and deliver it to our cells, where it is used to produce energy through a process called cellular respiration.

Chapter 3: The Firestarter

Oxygen also has another remarkable property - it supports combustion. It is the key ingredient that allows fire to burn. When oxygen combines with a fuel source, such as wood or gasoline, it reacts and releases heat and light. This process is known as oxidation or burning.

Chapter 4: The Ozone Shield

In the upper atmosphere, oxygen plays a crucial role in protecting life on Earth. It forms a layer called the ozone layer, which shields us from harmful ultraviolet (UV) radiation from the sun. The ozone layer acts as a protective barrier, preventing most of the sun's UV rays from reaching the Earth's surface.

Chapter 5: The Oxygen Cycle

Oxygen is not only produced by plants during photosynthesis but also released by marine plants and algae in the oceans. Through a process called the oxygen cycle, oxygen is continuously exchanged between the atmosphere, plants, animals, and the oceans. This cycle ensures a constant supply of oxygen for all living organisms.

Chapter 6: Oxygen in Industry

Oxygen has numerous industrial applications. It is used in the production of steel, chemicals, and fuels. In the medical field, oxygen is used to support patients with respiratory conditions and during surgical procedures. Oxygen is also used in water treatment plants to purify water and remove impurities.

Chapter 7: The Future of Oxygen

As we look to the future, the importance of oxygen remains unchanged. Scientists continue to study and explore its properties, finding new ways to utilize this remarkable element. From space exploration to medical advancements, oxygen will undoubtedly play a vital role in shaping our future.

And so, the tale of oxygen continues, with its remarkable properties and its indispensable role in the world. Remember to appreciate the air you breathe, for it carries the magic of oxygen, sustaining life and fueling the fires of discovery.
