Rev. E, 2006, 74, 041603 (1-22). The acoustic wave is focused, allowing the study of a small volume of liquid, far from any surfaces. We find a well defined threshold for the nucleation of bubbles (cavitation). Two methods of calibration agree to give a cavitation pressure which increases monotonically from -26 MPa at 0oC to -17 MPa at 80oC. These values are among the most negative reported for water, but fall far from the theoretical expectation (around -120 MPa at 40oC) which is thought to have been reached in one experiment with another method. We propose two alternative explanations. On one hand, cavitation in our experiment could be heterogeneous, occuring on impurities. We have performed a careful check of reproducibility and a detailed data analysis to investigate this possibility. On the other hand, the discrepant results can be brought into agreement if the equation of state of water at negative pressure is different from what is currently accepted. We describe our preliminary measurements to check this issue.
