...Water cannot be broken down into simpler substances by mechanical or physical means.
2...The composition of water is by chemical reaction between two pure elements Hydrogen and Oxygen in a fixed ratio and can only be broken down by chemical reaction.
3...The boiling and freezing temperatures of pure water are non-variable constants at standard atmospheric pressure.
4...A mixture is a combination of two or more substances that are not chemically combined and have no fixed ratio of components. Mixtures can be separated by physical or mechanical means such as Filtration, distillation, solution, magnetism....etc.
