Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible. Surface tension is what allows objects with a higher density than water such as razor blades and insects (e.g. water striders) to float on a water surface without becoming even partly submerged.
The US Institute of Medicine recommends that, on average, men consume 3 litres (0.66 imp gal; 0.79 US gal) and women 2.2 litres (0.48 imp gal; 0.58 US gal); pregnant women should increase intake to 2.4 litres (0.53 imp gal; 0.63 US gal) and breastfeeding women should get 3 liters (12 cups), since an especially large amount of fluid is lost ...
The polar nature of the hydroxyl group causes ethanol to dissolve many ionic compounds, notably sodium and potassium hydroxides, magnesium chloride, calcium chloride, ammonium chloride, ammonium bromide, and sodium bromide. [78] Sodium and potassium chlorides are slightly soluble in ethanol. [78]
Higher chloride levels require more highly alloyed stainless steels. Localized corrosion can be difficult to predict because it is dependent on many factors, including: Chloride ion concentration. Even when chloride solution concentration is known, it is still possible for localized corrosion to occur unexpectedly.
Dimers also occur in the liquid phase in dilute solutions with non-hydrogen-bonding solvents, and to a certain extent in pure acetic acid, [23] but are disrupted by hydrogen-bonding solvents. The dissociation enthalpy of the dimer is estimated at 65.0–66.0 kJ/mol, and the dissociation entropy at 154–157 J mol −1 K −1 . [ 24 ]
Alum, short for aluminum sulfate, is used in pickling to promote crisp texture and is approved, though not recommended, as a food additive by the United States Food and Drug Administration. [26] [27] Another common crisping agent is calcium chloride, which evolved from the practice of using pickling lime. [28] See also firming agent.
Louisville [b] is the most populous city in the Commonwealth of Kentucky, sixth-most populous city in the Southeast, and the 27th-most-populous city in the United States. [a] [11] By land area, it is the country's 24th-largest city, although by population density, it is the 265th most dense city.
