Answer:
are a result of hydrogen bonding.
Explanation:
The <em>surface tension</em><em> is the amount of energy required to stretch or increase the surface of a liquid by a unit area</em>. <u>Liquids that have strong intermolecular forces also have high surface tensions.</u> Thus, because of hydrogen bonding, water has a considerably greater surface tension than most other liquids.
Another example of surface tension is capillary action. A thin film of water adheres to the wall of the glass tube. The surface tension of water causes this film to contract, and as it does, it pulls the water up the tube. Two types of forces bring about capillary action.
One is <em>cohesion</em><em>, which is the intermolecular attraction between like molecules (in this case, the water molecules)</em>. The second force, called <em>adhesion</em><em>, is an attraction between unlike molecules, such as those in water and in the sides of a glass tube</em>. If adhesion is stronger than cohesion, the contents of the tube will be pulled upward. This process continues until the adhesive force is balanced by the weight of the water in the tube.
This <u>characteristics of water are a consequence of a particularly strong type of intermolecular attraction, called the </u><u>hydrogen bond</u><u>, which is a special type of dipole-dipole interaction between the hydrogen atom in a polar bond, such as N-H, O-H, or F-H, and an electronegative O, N, or F atom.</u>
Answer:
The law of the conservation of mass states that matter is neither created nor destroyed, only converted to other forms. Therefore, the mass never changes, even if its appearance does.
Explanation:
Answer: Yes, two objects may have the same volume while having different masses. The object with a greater mass will be the one that contains more matter.
Explanation: Mass and volume are two different properties of matter. Mass is defined as the amount of matter that a body has. Volume is defined as the amount of space that a body occupies. Density is the property that relates mass with volume as
and is defined as the amount of matter that exists in a certain amount of space.
Because mass and volume are independent from each other, we can say that two objects can have different masses and have the same volume.
<u>For example</u>, imagine two identical containers that weigh the same and that are capable of containing a volume of 1 liter each. Then, one of the containers is filled with water, while the other one is filled with mercury. In this case the volume of the water and the volume of the mercury will be the same: 1 liter, however, if we weigh the containers again, we will find that the one that has mercury is heavier than the one that has water. This is due to the density of mercury being higher than the density of water. In other words, 1 liter of mercury provides more mass than the mass provided by 1 liter of water.
Then, according to the definition of mass, the object that contains more matter will be the one that has more mass, in the case of our example, that would be the liter of mercury.
