Interesting facts about chemistry
Answers
Answer:
chemistry is a scientific discipline involved with elements and compounds composed of atoms and molecules and ions
Answer :
1. An apple, potato, and onion all taste the same if you eat them with your nose plugged .
2. Plastics are made from raw materials like natural gas, oil or plants, which are refined into ethane and propane.
3. The football-shaped carbon cluster C60 has been called ‘the most beautiful molecule’, and if you have an eye for symmetry it’s easy to understand why. But if you ever liked chemistry in school, or actually have a career working in chemistry, you know chemistry goes beyond ‘beauty’.
4. Ozone, the triple oxygen molecule that acts as a protective stratospheric blanket against ultraviolet rays, is created in nature by lightning. When it strikes, the lightning cracks oxygen molecules in the atmosphere into radicals which reform into ozone. The smell of ozone is very sharp, often described as similar to that of chlorine. This is why you get that “clean” smell sensation after a thunderstorm.
5. Most metals’ electrons reflect colors equally, so the sun’s light is reflected as white. Gold and copper, however, happen to absorb blue and violet light, leaving yellow light. It’s worth noting here that copper is also the only metal that is naturally antibacterial.
6. Typically, when something is cold, it shrinks. That’s because temperature describes atomic vibration — the more vibration, the more space it takes, hence expansion. Water is an exception. Even though it vibrates less when it’s frozen, the ice occupies more volume. That’s due to the strange shape of the water molecule.

8. Being neither liquid, nor solid, explaining glass is a lot harder than some might think. In a glass, molecules still flow, but at a very low rate that it’s barely perceptible. As such, it’s not enough to class glasses as a liquid, but neither as a solid. Instead, chemists classify glasses as amorphous solids— a state somewhere between those two states of matter. There’s also a thing called metal glass – a class of materials that are three times stronger than titanium and have the elastic modulus of bone, all while being extremely lightweight.
9. Every hydrogen atom in your body is likely 13.5 billion years old because they were created at the birth of the universe.
10. If you pour a handful of salt into a glass of water, the water level will go down
11. Diamond and graphite are both entirely made of carbon and nothing else
12. One inch of rain is equal to 10 inches of snow
13. The rarest naturally-occurring element in the Earth’s crust is astatine.
14. Famed chemist Glenn Seaborg was the only person who could write his address in chemical elements.
15. Air becomes liquid at -190°C.
