Tendances

It reasonably can be argued that that most participants in the roofing, building and design trades tend to either take water for granted or lack the basic understanding of both the chemistry and physics that play such a large role in water accumulation within a building enclosure. Sure, people in the construction business fear the effects of excess water, but few have taken the time to understand why it acts the way it does. The driving forces that cause moisture movement are fundamental properties of nature; therefore, preventing water infiltration and resulting damage at the typical building project requires close attention during the design and construction processes to all potential moisture sources and routes. Seven fundamental aspects of water are presented in Water 101 to provide Trinity | ERD forensic personnel and our clients an essential knowledge base for the physical properties of water.

explain why these three properties of water are important? melting and freezing cohesive and adhesive An excellent solvent Solution Water melting and freezing properties are important because these properties are main colligative properties useful to prepare polar biological & pharmaceutical products suitable to the internal human body environment The cohesive forces (cohesion) & adhesive forces of water molecules enable to acquire elastic tendency with considerable surface area promote solubility. This tendency is referred as surface tension. Surface tension of any fluid decreases with increasing temperature. This is due to existence of cohesive intermolecular forces between molecules of the fluid is reduced and it is based on the surrounding environment with adhesive intermolecular forces & viscosity of the fluid, molecular thermal activity at the liquid interface For example, water is a universal solvent and it has both polar because it has both positive charge (H+ or H3O+) and negative charge (OH-). This polarity enables water to make substances to dissolve in it as charged species. On the other hand, water molecules possess a higher attractive power to each other so that these forces are referred as cohesive forces responsible for “surface tension” phenomenon” and these attractions are predominantly due to hydrogen bonding. For instance, 2 to 3 drops of water between the cover slip is imparted adhesive forces (another example is capillary rise due to forces between glass and water in capillary tube) between the two glass cover slips result in adhesion instead of cohesion that potentially differentiate intermolecular forces between two different substances namely water and silicon. These intermolecular forces render glass surface as hydrophilic. These intermolecular forces are decreased as the temperature increases due to increase in molecular thermal activity of the fluid molecules ate the interface of water molecules. An excellent solvent Water is a universal polar solvent and it has hydrogen bonding associated with highest heat capacity and is referred as “specific heat capacity”. This specific heat is predominantly due to intermolecular and intermolecular hydrogen bonding. In nature on land when heat is absorbed result in breaking of hydrogen bonds specifically followed by production of heat. Normally ocean water cool little bit slower when compared to the land water because of more heat capacity. This sterile solvent has ability to dissolve a majority of biological products to prepare pharmaceutical products finally used as diluents in saline, injectables etc. Water properties and the biological importance of water: 1). Due of the presence of hydrogen bonds and strong intermolecular forces, water has high specific heat index. Specific heat capacity of water is defined as; the amount of heat (energy in joules) required for raise of temperature of water per unit mass by 10C. Our body temperature is maintained higher than the surroundin.
