The action of pressure on fluid molecular structures

Since the formulation of Boyle's law in the seventeenth century and the Florence Academy's compression tests to evaluate the compressibility of water , pressure has been a central thermodynamic parameter in the world of chemistry and the physics of inorganic and living matter. Combined with temperature, pressure is routinely used to explore the response of chemical systems in their various thermodynamic states. In fact, the great interest in pressure lies in the fact that its energetic impact far exceeds that of temperature, thanks to the importance of the compression effect achieved on a chemical system. This compression effect is achieved by the technical means currently available, such as diamond anvil cells (DAC), multi anvil presses (ME), shock techniques...

This article studies the effect of pressure on molecular liquids and fluids. The article presents the action of pressure on solid molecular structures.
