4. : Applications: Sonochemistiy Sonofusion Sonodynamic therapy

5. Physical and SL properties of some liquids:

6. Why sulfuric acid ? Higher intensity Appearance of line emission in spectrum

7. Hydrodynamics model: Bubble dynamics: boundary condition of pressure and Van der waals equation of gas:

8. Chemical reaction:

9. 14/17 Mass transfer at the bubble wall: The bubble contents is assumed to be: ( Nobel gas+H 2 O+ Reaction products )
