an undissociated dilute solution can be found from the viscosity of the solution and of the pure solvent‚ and from the rate of diffusion of the solute into the solvent‚ if the volume of a molecule of the solute is large 36 ’ 37 compared with the volume of a molecule of the solvent. For such a sofute molecule will behave approximately‚ with respect to its mobility in the solvent‚ and in respect to its influence on the viscosity of the latter‚ as a solid body suspended in the solvent

ABSTRACT Concrete has been the most preferred construction material for over five decades. It is being increasing day to day all over the world due to its versatility‚ mould ability‚ high compressive strength and many more advantages. For several years beginning in 1983‚ the problem of the durability of the concrete structures was a major topic of interest in Japan. The creation of durable concrete structures requires adequate compaction by skilled workers. One solution for the achievement of durable

depends on the heating method‚ time‚ uniformity‚ and other factors. If the oil processing machinery have heat on oil‚ then the change of oil viscosity and oil binding. Steam heating effect of the process of speculation‚ make the billet in high temperature‚ and weaken the enhanced oil thermal motion of molecules and molecular cohesion‚ resulting in green oil viscosity and surface tension reduction‚ weakening the binding of grease and part of the green gel and enhance the mobility of the oil‚ oil get rid

AP Chemistry Chapter 13 Outline Condensed phases: the liquid and solid phases; phases in which particles interact strongly. 13.1 Gas condensed when cooled and compressed. In the liquid state the forces of attraction among particles are great enough that disordered clustering occurs. It is hard to compress a liquid. Liquids diffuse into other liquids with which they are misicible. The natural diffusion rate is slow at normal temperatures. Cooling a liquid lowers its molecular kinetic energy

The characteristic properties of slime can be explained by polymerisation reactions. Polymers can be explained most simply by the polymerisation of the molecule ethylene into polyethylene (see figure 1 below). Figure 1. Polymerisation of polyethylene from ethylene. In this example‚ the double bond between the carbon atoms is broken‚ allowing each carbon atom to form one more bond between another molecule. The double bond between the carbon atoms is weaker because the type of orbital is ‚ compared

Intermolecular Forces Intermolecular Forces Lab II. Goal: The central goal of this experiment is to depict the intermolecular forces of four different properties of solubility‚ evaporation‚ viscosity‚ and boiling point. The reason for achieving the goal is so we can further understand solubility‚ Evaporation‚ viscosity‚ and the boiling point of liquids. III. Experimental procedures In this Lab there were four different stations to experiment with‚ my partner and I started with grabbing our goggles

Example of a mutualistic relationship An example of a mutualistic relationship in the Daintree rainforest is the relationship between the Ulysses butterfly and the pink flowered doughwood. This relationship is mutualistic because the pink flowered doughwood needs a specific insect pollinator‚ the Ulysses butterfly‚ and the Ulysses butterfly relies on the pink flowered doughwood for the nectar on which it survives‚ making them both benefit and rely on each other. Example of a commensal relationship
