True or false? Intermolecular cohesive forces are nonexistent in ideal gas systems.Ideal Gas Assumptions:When we refer to ideal gases, we are referring to gases at high temperature and low pressure. These conditions make several assumptions possible to simplify calculations. Some ass...
Polar molecules, such as water (H2O), form structures in which the positive charge on a molecule is close to the negative charges of its neighbors. For nonpolar molecules, the electrostatic interactions are usually weaker than the van der Waals forces. The nonspherical interactions in such cases...
in the process, such as sedimentation and consolidation, have not been fully accounted for yet, so that studies are necessary to explain the mudflat formation process. Toorman and Huysentruyt (1997) proposed a constitutive equation for effective stress in self-weight consolidation, their model ...
Cohesion, in physics, theintermolecular attractive force acting between two adjacent portions of a substance, particularly of a solid or liquid. It is this force that holds a piece of matter together. Intermolecular forces act also between two dissimilar substances in contact, a phenomenon called ad...

It is doubtful whether any of the classical soil mechanics tests for shear strength give the true measures of these forces. Nevertheless, ch has been used as a convenient parameter and a reasonable measure. The plastic and cohesive properties of fine sediments are due to that part of the soil...
The last term is the linear forcing term that was used to drive the isotropic turbulence62. The above equations are solved in non-dimensional forms. Numerical setup and simulation parameters We solve the governing equations in a non-dimensional form. The fluid phase was modeled using Direct numer...
We study the effect of fluids on the angle of repose and the segregation of granular matter in two experimental systems. In the regime where the volume fraction of the introduced fluid (liquid) is small, liquid bridges between particles are formed thus giving rise to cohesive forces between par...
The cohesion and anisotropy in dense, cohesive powders was studied by using a discrete element method for the simulation of a biaxial box deformation. The approach includes normal (repulsive/cohesive) as well as tangential forces. Reorganization of the contact network first leads to anisotropy and ...
Here we describe a class of cohesive granular materials with tunable properties, and characterise the mechan- ical response of these materials to uniaxial compression. The materials are similar to wet granulates, like sand, but where the liquid in the capillary bridges between adjacent grains has ...
