Water Quizzes Online & Trivia

Capillary action is a special property of the water molecules, which is due to the water molecules adhering to one another. When these water molecules are applied to a tube like structure such as the root or vessel wall causes an upward force. This causes the liquid to move up the tube. This is possible due to the surface tension on the water surface due to adhesion between water molecules. This causes the surface of the water to become unbreakable. The capillary action results because the force between the walls of the tube and the water molecules is much higher than the forces between the liquid molecules.

The answer to this question is E. This polar bear is relying on the density of the water in relation to the ice cap. The density of water is what allows all things, including animals, to float. Since this polar bear is standing on a small ice cap which is floating, the density of the water is what is allowing the bear to stay afloat. This shows that the ice cap has a higher density than the water it is floating on. If something with a higher density than water is placed in water it will sink to the bottom. Therefore this ice cap must have a lower density than the water below.

Water is an essential element, and it is necessary for all forms of life. Water covers approximately 70 percent of the surface of the earth. Vinegar, which is a versatile liquid, is formed as a result of the formation of ethanol. A molecule of water is comprised of two hydrogens and one oxygen atom, while a molecule of vinegar consists of two carbon, two oxygen, and four hydrogen atoms. Water has a neutral PH, while vinegar has a PH value that is gauged between 2 and 3.5. Unlike vinegar, water can change from its natural state from a liquid into a solid when it freezes. Also, water is not acidic, but vinegar is highly acidic and potent.

The Friction loss of the 150' line is 18.75 psi, the friction loss in the 400' line is 50 psi for a total of 68.75 psi. so what am i missing?

There is not enough weight to break the hydrogen bonds between water molecules at the surface of the water

A is the answer to this question. Specific heat is known to be the amount of heat that is available for every unit of mass. This is needed in order to increase the heat of a specific element or item. Heat and temperature changes are related to each other. There are some that are not too hot but because of exposure, the amount of heat will also increase. The increase in temperature is also connected to the average value of the kinetic energy of the atoms and molecules. The other choices available refer to the different characteristics of water that will not play any role in providing warmth and insulation.

Sea water is the best conductor of electricity because it has a high salt content. Salt molecules are made of sodium ions and chlorine ions. When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water. Pure water is not very conductive, and only a tiny bit of current can move through the water. When salt or sodium chloride (NaCl) is dissolved in it, however, the salt molecules split into two pieces, a sodium ion and a chlorine ion. The sodium ion is missing an electron, which gives it a positive charge. The chlorine ion has an extra electron, giving it a negative charge.

The human body has certain defenses for itself in specific situations. One such defense is the ability to sweat should the body temperature need to be cooled quickly. Most animals do not have large numbers of sweat glands like humans do. Only primates and horses have large concentrated sweat glands the way humans do. The polarity of water allows water to have a high specific heat which allows us to maintain or return to homeostasis when we sweat. This is one of the things that allows humans to survive as we are today.

The correct answer to this question is C, intertidal zone. This zone is also known as a foreshore, seashore, and littoral shore. Intertidal zones are areas that are either above water at low tide or underwater at high tide. Along with starfish, they are the habitats of other animals such as sea urchins and corals. These animals are used to living in the zone, which has extreme climates. Intertidal zones include cliffs, beaches that are sandy, and wetlands. They are divided into three zones, low, middle, and high and examples of intertidal zones are Bancao Beach and the Pacific Islands.

Tornadoes that form over water are called waterspouts. There are three categories of waterspouts: tornadic waterspouts which form downward over water and have the probability to move from land to water, fair weather waterspouts which move very little, usually upward, since they only form in light wind conditions and snowspout or winter waterspout which forms during winter and under the base of a snow squall. Studies revealed that waterspouts have a five-part cycle – the first one is wherein it forms over a dark spot on the surface of the water, then once formed it will spiral to the water surface, form a spray ring, after which it will develop a condensation funnel which is visible, and then it will dissipate afterwards.

Coesion which is the ability of water molecules to attach to other polar substances
