4 days ago · Here, we build on the first two activities by now considering ways in which matter can be changed. In science there are two types of changes pupils should consider: reversible changes – called physical changes; irreversible changes (changes that cannot easily be reversed) – called chemical changes.
4 days ago · The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed and the uniformity of their composition. A homogeneous mixture is a mixture in which the components that make up the mixture are uniformly distributed throughout the mixture. On the other hand, a heterogeneous mixture is a mixture in ...
