Abstract

To comprehensively understand molecular processes, it is essential to analyze how thermodynamic parameters change with temperature and composition, providing valuable insights into molecular interactions. The industry's demand for precise information on the physical and chemical characteristics of different liquid combinations underscores the importance of such research. Researchers employ an ultrasonic interferometer for measuring ultrasonic wave velocity, a specific gravity bottle for liquid density determination, and an Ostwald viscometer for viscosity measurements. The propagation of ultrasonic waves can affect the physical properties of a medium, providing insights into the physics of liquids and solutions. Research has explored how frequency and temperature can impact thermoacoustic characteristics. Scientists have identified the nature of the forces between molecules, including hydrogen bonds, charge transfer complexes, and the breaking and formation of such bonds through their investigations. By measuring ultrasonic wave velocity, liquid density, and viscosity, researchers can analyze a range of acoustic and thermodynamic properties, thus significantly advancing our understanding of molecular interactions within each sample. Additionally, a comprehensive explanation of the measured parameters is provided to offer detailed insights into the studied phenomena, enhancing the overall understanding of molecular processes in liquid mixtures.
