Mechanical and chemical effects caused by cavitation fall into three different processes (Figure 3). First, the cavitation bubble contains solvent vapour which is subject to high temperatures and pressures on collapsing. This promotes the formation of reactive species, e.g. radicals. For example, when water is used as solvent the following reactions take place:

H2OPH • # • OH H • # OH • PH2O H• # H• PH2 OH• # OH• PH2O2 H • # O2PHO2 • H• # O2PHO2• H • # H02 • PH2O2 H02 • +H02 • pH2O2#O2

Second, surface-active reagents can accumulate at the interface between the bubble and the bulk liquid. Finally, in the surrounding of the bubble, an intense shock wave will be produced causing enormous shear forces.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
