Respiratory or skin sensitization. The density of water is maximum at 4^(@)C. Moreover use of hard water in industries results in to scale formation in inner layers of boilers on which insoluble calcium and magnesium carbonates gets deposited and being a bad conductor of heat result in to wastage of energy. Question: Which of the following statements about water is not correct? Book Contents Navigation. Buffers readily absorb excess H+ or OH–, keeping the pH of the body carefully maintained in the aforementioned narrow range.
You have probably used litmus paper, paper that has been treated with a natural water-soluble dye so it can be used as a pH indicator, to test how much acid or base (alkalinity) exists in a solution. As more and more countries adopt the principles of GHS, the benefits include: - Promoting regulatory efficiency. Therefore, water is denser in liquid form than when it freezes and becomes a solid form. Water has a high heat of fusion. Learn about the physical and chemical properties of water. Solved] Which of the following statements is true? Question 14 options:... | Course Hero. The environment in your stomach is highly acidic (pH = 1 to 2).
4 Landforms of Coastal Deposition. For similar questions refer to: There are categories where no signal word is used. Note that the amendment of the HPA and implementation of the new HPR is based on the fifth revised edition (Rev 5). Most alkyl amines are more basic than ammonia solution. Which of the following statements about water is NOT correct? - Myschool. AWater is less dense in its solid form than it is in its liquid form. So, the answer to this question is C. Kinetic energy is transferred mostly from the hot water to the cold water, or to the ice, I should say.
In lakes, ponds, and oceans, ice will form on the surface of the water, creating an insulating barrier to protect the animal and plant life beneath from freezing in the water. 1 Latitude and Longitude. Which of the following statements about water is not correct based. Chapter 4: Plate Tectonics and Marine Geology. Evaporation: the release of water molecules from liquid water to form water vapor. Bonds are constantly being formed and breaking up. 1 Overview of the Oceans. EWater has an unusually high boiling point.
E. Has a relatively low heat capacity. While existing systems were similar in many respects, their differences were significant enough to result in different hazard classifications, labels, or SDS for the same product. Which of the following statements about water is not correct type. It is because water is essential to life; even minute traces of it on another planet can indicate that life could or did exist on that planet. For example, hydrochloric acid and lemon juice are very acidic and readily give up H+ when added to water. This problem has been solved!
Classification of Elements and Periodicity in Properties. The UNECE publishes information about the status of implementation of GHS by country. Water has high specific heat capacity, due to which, when the high energy hydrogen bonds break and releases heat, it will be absorbed by water. Skin corrosion/irritation. 7 Classifying Elements in Seawater. For example, if a country adopts the flammable hazard class and only the Category 1 level, the criteria for Category 1 will be the same for all the countries that adopted this Category. Hard water cannot be used for washing purposes as soap do not form lather with hard water easily which results in to wastage of soap in laundaries. For both mineral and organic substances, water is a good solvent, which makes it suitable for cooking and washing. Which of the following statements about water is not correct using. Answer: [D] I, II, III and IV. Therefore, the more hydrogen ions present, the lower the pH; conversely, the fewer hydrogen ions, the higher the pH. Thus, small changes in pH represent large changes in the concentrations of hydrogen ions.
Evaporation of sweat, which is 90 percent water, allows for cooling of an organism, because breaking hydrogen bonds requires an input of energy and takes heat away from the body. What are the classes within the Environmental hazard group? This adoption will help make sure that each country has the same classification criteria as each other. Notice the empty spaces within the ice structure. Motion, unlike ice which is a rigid lattice structure (above).
