Water turns into gaseous water vapor under certain conditions, and ice turns into water under certain conditions.
First, water can turn into water vapor, which is carbonated water. As the temperature of water increases, the water molecules become more active and the interaction between the molecules weakens, causing the water molecules to leave the surface of the liquid and become gas molecules. At high temperatures, water molecules can quickly change from liquid to gas and can even boil within seconds. Water vapor can also be cooled further to become liquid water.
On the other hand, solid water is called ice or snow, which is a crystal formed by the ordered arrangement of water molecules. When water temperature drops below freezing, water molecules become more ordered and form a lattice structure, forming ice or snow. As temperatures continue to drop, ice or snow becomes harder and more solid. Ice can also be transformed into liquid water by heating.
Finally, liquid water is a state in which water molecules are arranged disorderly in three-dimensional space. When water is subjected to disturbance or pressure, the interactions between molecules are broken, resulting in an ordered arrangement of water molecules in three-dimensional space, a liquid crystal. Liquid crystals can exist in a specific temperature range and exhibit particular properties, such as optical anisotropy, fluidity, etc.
Characteristics of water
1. Three-State Changes in Water: Water can change between the three states of solid, liquid, and gas. This is the first characteristic. When water is heated, itIt changes from a liquid to a gas, and when it cools, it changes from a gas to a liquid.
2. Water solubility: Water can dissolve various substances, such as salt, sugar, proteins, etc. In nature, water also has the property of purifying and diluting pollutants.
3. Surface tension of water: Surface tension of water refers to the mutual attraction between water molecules, which can give droplets a spherical shape. This property has many applications in daily life, such as the design of faucets, the making of soap bubbles, etc.
4. Water Mobility: Water can move freely through the container without obstruction. This property is important in nature, for example where water flows create rivers and oceans.
5. Water Conductivity: Pure water does not conduct electricity, but when water contains impurities, it can conduct electricity.'electricity. In industry, water is widely used to cool and transmit electrical current.
6. Water stability: Water is very stable at normal temperature and pressure and is not easy to decompose or deteriorate. However, high temperature or high pressure environments can change the chemical properties of water.
7. Water Diversity: Water on earth has different forms and states, including sea water, fresh water, ice, snow, etc. These different forms and states have different physical and chemical properties.
Scientists have discovered that under particular conditions, water can exhibit many interesting properties. If a weak electric field is applied to water under certain conditions, water will form at normal temperature and pressure.
Water will turn into ice, fog, water vapor, snow and rain in certain conditions;
1. Ice is a colorless and transparent solid. Molecules are mainly connected by hydrogen bonds. The network structure is generally hexagonal, but it can have other network structures according to different pressures. the water. Under normal pressure, the melting point of ice is 0 degrees. When water freezes to ice at 0 degrees, its volume increases by about one-ninth; When there is enough water vapor, when the relative humidity reaches 100%, when the wind is gentle and the atmosphere is stable, the water vapor in the air condenses into fine droplets. water suspended in the air, thereby reducing visibility at ground level. The weather phenomenon is called fog. The first condition is cooling and the second is humidification to increase the water vapor content.
3. Water vapor, called water vapor, is; the gaseous form of water. When the water reachesthe boiling point, water turns into water vapor
4. Solid water in the form of snowflakes falling to the ground from mixed clouds ; , precipitation composed of large numbers of opaque white ice crystals and their polymers, snow is the natural phenomenon of water condensing in the air and then falling, or falling snow, a form of water in the solid state
5. Rain is a natural phenomenon of precipitation. It is produced by disturbances in atmospheric circulation and is the only way for almost all land plants away from rivers to replenish themselves with fresh water.
A. Water turns into ice molecules without changing, which is a physical change, so A is correct;
B. According to the question: Applying a weak electric field to water under certain conditions will often push the water downward to form ice, commonly referred to as "hot ice”. Therefore, an ice rink can be built at normal temperature and pressure, so B is correct;
C． 1 mole of water contains 10 moles of electrons. A water molecule can release an electron and produce an M+ cation at the same time. 1 mole of M+ contains 9 moles of electrons, so C is correct;
D. . M+ is expected to have strong oxidizing properties. It is difficult for water to lose electrons under normal circumstances, but this unstable particle should easily gain electrons and become water molecules, so D is false.
Then choose D.
