Facts of chemistry:- 

• The only solid elements that become liquid at room temperature are bromine and mercury. However, you can melt the gallium by holding the lumps in the warmth of your hands. 
• Unlike many substances, water expands when it freezes. Ice cubes occupy about 9% more volume than the water used to make it. 
• Pour a handful of salt into a glass of water and it will actually lower the water level instead of overflowing. 
• If you mix 0.5 liters of alcohol and 0.5 liters of water, the total amount of liquid will be less than 1 liter. 
• The average adult human body contains about 0.4 pounds or 200 grams of salt (NaCl). 
• Pure elements take many forms. For example, diamond and graphite are both in the form of pure carbon. 
• Many radioactive elements actually glow in the dark. The chemical name for water (H2O) is dihydrogen monoxide. Only J is not on the periodic table. 
• A lightning strike produces ozone, O3, which strengthens the ozone layer of the atmosphere. 
• There are only two metals other than silver, gold and copper. Oxygen gas is colorless, but liquid and solid oxygen are blue. 
• The human body contains enough carbon to supply "lead" (actually graphite) to 9,000 pencils. 
• Hydrogen is the most abundant element in the universe, and oxygen is the most abundant element in the Earth's atmosphere, crust, and ocean (about 49.5%).  
• Perhaps the rarest natural element in the Earth's crust is astatine. It seems that the entire crust contains about 28 grams of elements.
• Hydrofluoric acid is highly corrosive and will melt the glass. Although corrosive, hydrofluoric acid is considered a weak acid. 
• A bucket of water contains more atoms than a bucket of water in the Atlantic Ocean. 
• Helium is lighter than air, so the helium balloon floats. Bee stings are acidic, but bee stings are alkaline. 
• Chili peppers get heat from a molecule called capsaicin. 
• This molecule stimulates mammals, including humans, but birds lack the receptors responsible for their effects and are unaffected by the burning sensation. 
• Too much water can kill you. Dry ice is a solid form of carbon dioxide (CO2). 
• Liquid air has a bluish tint, similar to water. It cannot be frozen simply by cooling helium to absolute zero. 
• It freezes when very strong pressure is applied. By the time you feel thirsty, you have already lost about 1% of your body's water. 
• Mars turns red because its surface is rich in iron oxide and rust. 
• Hot water may freeze faster than cold water. High school students recorded the effect

The Most Expensive in the World: - 

Friends, you are our antimatter article, the most expensive one in the entire universe is antimatter, which is absolutely correct. Yes, my friend, I tell you I should write a letter, I will tell you about the most expensive things in the world. But do you know the most expensive things made by man? If you haven't heard. The most expensive man-made product in the world is the endohedral fullerene. A gram of this substance is worth 964 rupees in Indian currency. Yes, that's true, substances are the most expensive in the world.

Drinking too much water can kill you: - 

You've probably heard about drowning in water, but did you know that drinking too much water can kill you? I just write that if you drink too much water you can die. It seems that drinking too much water can lead to death.

I can't taste it even if I have taste buds :- 

You all need to know that there are taste buds on our tongue, yes, friends, I'm right to say so. What you are, and without saliva, you can't taste anything. ,. Yes, my friend, I correctly say in this fact. You can't taste it without saliva. It can't taste anything.
