Equation of State of Ballistic Gelatin

Abstract

We determined the equation of state for ballistic gelatin using the Brillouin scattering spectroscopy with a diamond anvil cell by measuring the pressure dependence of the sound velocities from ambient pressure to 12 GPa at room temperature. We extended these measurements to a temperature range of 0 to 100 deg C between ambient and 12 GPa. We analyzed the Brillouin data using a high temperature Vinet equation of state and obtained the bulk modulus, its pressure derivative, thermal expansion coefficient and the temperature derivative of bulk modulus at ambient pressure.
