“…( 11) are computed from the density measurements [4,7,16]. Figure 1 shows that the internal pressure decreases as the temperature increases and possesses a negative thermal pressure coefficient, which is consistent with the results reported for ethyl caprate [12] and methyl linoleate [18]. To the best of our knowledge, the study of internal pressure as a function of temperature in biofuels has hardly been investigated.…”

In the present study, an approximation is applied to study the sound speed in liquids as a function of pressure at different temperatures. The relation obtained is applied in the case of biofuel component liquids. The calculated results for each liquid were found to be in good agreement with the experimental results throughout the range of pressure and temperature. The maximum percentage error and average percentage error are not more than 5.2 and 1.9, respectively, in the entire range of pressure and temperature for all liquids. Furthermore, the internal pressure and nonlinear Bayer's parameters are also computed as a function of temperature at one atmosphere from sound speed for the first time in biofuel component liquids.

How Water’s Properties Are Encoded in Its Molecular Structure and Energies

How are water’s material properties encoded within the structure of the water molecule? This is pertinent to understanding Earth’s living systems, its materials, its geochemistry and geophysics, and a broad spectrum of its industrial chemistry. Water has distinctive liquid and solid properties: It is highly cohesive. It has volumetric anomalies—water’s solid (ice) floats on its liquid; pressure can melt the solid rather than freezing the liquid; heating can shrink the liquid. It has more solid phases than other materials. Its supercooled liquid has divergent thermodynamic response functions. Its glassy state is neither fragile nor strong. Its component ions—hydroxide and protons—diffuse much faster than other ions. Aqueous solvation of ions or oils entails large entropies and heat capacities. We review how these properties are encoded within water’s molecular structure and energies, as understood from theories, simulations, and experiments. Like simpler liquids, water molecules are nearly spherical and interact with each other through van der Waals forces. Unlike simpler liquids, water’s orientation-dependent hydrogen bonding leads to open tetrahedral cage-like structuring that contributes to its remarkable volumetric and thermal properties.

“…The study of sound speed in water becomes still more important due to fact that it exhibits a maximum near 76 0 C. Some empirical relations [1][2][3][4] are available in literature to study the speed of sound in water as a function of temperature but no model or theory is available so far. Though, a model [5][6] is available to study the pressure dependence of speed of sound in liquids. Therefore, the aim of present paper is to study the temperature dependence of speed of sound in water based on two-state theory.…”
