At Miracle Learning Centre, in our Chemistry classes, the most enjoyed and exciting segment is the fun facts session. Our students eagerly wait for these sessions as they are highly knowledgeable and give them a lot of excitement and fun.
We offer courses of A level chemistry tuition, O level chemistry tuition, JC chemistry tuition in Singapore. Hi, and welcome back to your Science Tuition. We hope you have been having fun and learning from our recent lectures.
Today, in your Science Tuition, we are again going to provide you with our chemistry mysteries, hope you are ready for today’s’ dose of facts. Here we go:
- Did it ever occur to you if air could change its state and become liquid? No? Didn’t think of the impossible? Well, that is true. Air can become liquid when it is at 190-degree centigrade. Liquid air has a pale bluish tint, which is almost exactly like water.
- You know how dangerous explosives are, but did you know dynamite contains peanut as one of its ingredients? That’s quite funny, isn’t it? The reason behind it is that glycerol can be obtained from peanut oil which helps in the making of nitroglycerine, an explosive liquid used in dynamite.
- If you pour a handful of salt into a full glass of water, the water level will actually go down rather than overflowing the glass. Amazing isn’t it?
- Our body contains about 250g of table salt!!
- How does a metal melt? When it is heated right? But what if we tell you that there is a metal which can melt on the palms of your hand? Yes there is one. Galium is a metal which melts at 29.76 degree Celsius and it can melt on the palms of your hand.
- DNA doesn’t catch fire! Every human has 99 percent of their DNA is common! Everyone’s our relative?? He he. Your parent and you have 99.5 percent of the same DNA. But that’s not all, you have 98 percent of the same DNA of a chimpanzee!!
- You thought that Match Sticks were invented before a lighter right? But sorry you are wrong. The lighter was invented before the match in 1816 by J.W. Dobereiner.
- When we feel thirsty we have already lost about 1% of our body’s water!!
