PropertiesThe Physical Properties of Water are as follows:_ Density: Water has a density of exactly 0.9999 at 20%ºC, these measurements reflecting the density of water they were carried out since very ancient times with great precision. When water turns into ice, at constant temperature, the density decreases by 10% due to the expansion that occurs in this phase change._ Surface tension: The water molecule has a great attraction between molecules on its surface, thus creating surface tension. Furthermore, the surface of the liquid behaves like a film capable of stretching and at the same time offering a certain resistance in an attempt to break it. Due to its high surface tension, it is strongly influenced by capillarity phenomena. Drops of water also have stability at blood pressure._ Viscosity: Water has a viscosity at room temperature of 20ºC and at the boiling point of (100ºC), since it follows that the viscosity of water decreases with increasing of temperature and in relation to pressure, viscosity decreases with increasing pressure, being the only liquid known to present this anomaly._ Compressibility: water has a compressibility of great interest, since if it were zero, the level in ocean waters on Land would be about more than 40 meters high, so the total area of ​​non-submerged land would be reduced by half. The compressibility coefficient has a much lower value at ordinary temperatures and pressures. Specific Heat: Water has a specific heat which is defined as the amount of energy needed to raise the temperature up to one. gram of......middle of paper......between these and other polar molecules, so it becomes responsible together with the capillary cohesion 4) A high dielectric constant: Water, since it has dipolar molecules, is a excellent solvent medium for ionic compounds, such as mineral salts and polar covalent compounds. Water molecules, because they are polar, are arranged around the polar groups of the solute, splitting the ionic compounds into anions and cations, which they are surrounded by. water molecules. This phenomenon is called ionic solvation 5) A low degree of ionization: In general, out of 107 molecules, only one is ionized. This explains why the concentration of hydroxyl and hydronium ions is very low.6) Water is a weak electrolyte that has the ability of hydration, as well as solvation of ions..
