It is experimentally demonstrated for the first time that the temperature variation of the cavitational strength of water exhibits an extremal character with a minimum at 35-40 °С and a maximum near 50 °С. The further increase in the temperature is accompanied by decreasing cavitational strength and increasing absorption of the shock waves. A mechanism explaining this phenomenon is proposed, which is based on the concept of microscopic gas bubbles retained by convective flows, the velocity of which grows linearly with the temperature and exceeds the velocity of equilibrium bubble flotation at 50 °С.
