Temperature dependence of the Velocity of sound in liquids
Principle: Sound waves are radiated into a liquid by an ultrasonic transmitter and detected with a piezoelectric transducer. The wavelength of the sound is found by comparing the phase of the detector signal for different sound paths and, when the frequency is known, the velocity of sound as a function of the temperature of the liquid is determined.
Tasks: The wavelength is found from the phase position of the sound pickup signal relative to the generator signal as a function of the sound path and the velocity of the sound is determined when the ultrasonic frequency is known. The measurement is made for water and glycerol as the temperatures of the liquids are changed step-by-step.
