Çekmece Nuclear Research And Training Center.http://kurumsalarsiv.tenmak.gov.tr/handle/20.500.12878/576TENMAK D.N.. 8151The sound velocity has been measured in twice distilled water between 1-40°C with 0.5°C temperature intervals. The differences between the calculated velocities using a fifth degree polinom which was obtained by a computer and the measured velocities were plotted as a function temperature. It was noticed that at some temperatures this curve has not a random distribution character. The investigations showed that, at same temperatures Qurashi and Ahsanullah observed a series of discrete jumps in the activation energy of viscous flow of water, and Ahsanullah found discontinuities in the thermal expansion of water. The relationships among those three phenomens were investigated.enginfo:eu-repo/semantics/openAccessSoundSesUnderwater acoustics -- SpeedSualtı akustiği -- Hızreport
