Acoustic Study of Aqueous Polyethylene Glycol

Using measured values of ultrasonic speed, density and viscosity different acoustical parameters have been calculated like acoustic impedance and ultrasonic absorption. The speed of ultrasonic waves has been measured in aqueous solution of polyethylene glycol at 1 MHz frequency. Measurements were carried out at temperature 35C, at different concentration range 0.3 % to 1.0 %. By using these values intermolecular interactions are discussed.
