Today, we know this isn't true. In theory, if you had a knife small and sharp enough, you could chop an atom of gold into bits and you'd find smaller things inside. But then you'd no longer have the gold: you'd just have the bits. All atoms are made from the same bits, ...
He was the first person to find out that things float because the waterpushes them up. How well something floats or sinks depends on how much ofthe object rests in the water and what the object is made from. People believethat Archimedes started thinking about this problem while he was ...

The natural essence of things needs to be extracted and sublimated based on...
We are made of atoms that contain electric charges. Why we do not feel any electric force in our daily life?Atom:In chemistry, the atoms can be described as the tiniest particle which contains nucleus at its center around which particles having neg...
Everything you can see, touch, smell, feel, and taste is made of atoms. Atoms are the basic building-block of all matter (including you and me, and everyone else you’ll ever meet), so if we want to know about what Earth is made of, then we have to know a few things about ...
These forces are the reason why objects behave as they do at present, but things may be different in the distant future. It is now generally accepted that the expansion of the universe began accelerating about 4 billion years ago. The cause of this acceleration is dark e...
He could see that the best way to explain how air and other gases behave is to suppose they are made up of atoms. He could also see that the law of definite proportions made sense if you suppose all the elements are made up of atoms. Dalton studied the combination of elements on his...
