Everything we can see and touch, and quite a lot that we can’t as well, is made of tiny particles called atoms. Some substances, like particles of this iron, contain only one kind of atom. Iron is an ...

Dielectric properties of ionic and binary mixtures offer a critical insight into the interplay between molecular polarisation, ion dynamics and intermolecular interactions. In such systems, the static ...

In a sample of impure salol (salol mixed with other substances), the temperature falls gradually as it freezes. We can use these differences between melting and boiling points to distinguish between ...
