What do you know about the size of the molecules?

The molecules are very small in size, with a diameter of approximately 0.0000000001m. The smallest particle of any substance is called a molecule of a substance. Molecules cannot be simply seen even with an ordinary microscope, so there are electron microscopes that can photograph not only a molecule, but also atoms. For example, let’s imagine that we decided to put 10,000,000 water molecules close to each other, then in the end we get only 2 millimeters in length. In addition, the molecules also consist of smaller parts – the so-called atoms.
