Ice is solid, water is liquid, water vapor is gaseous, then fire is ???? Please, thank you

According to the law of conservation of mass and energy, fire does not make the combustible object disappear, but only transforms its molecular form through chemical reaction. In addition, fire is a substance, and fire appears in the form of a plasma that can take different shapes with the vibration of particles.

Liquid water begins to solidify into ice when it reaches (0), and solid ice can turn back into liquid water at (0).

The process by which water becomes ice occurs is a physical change in which the volume increases, but the mass does not change.

Physical change refers to the fact that although the state of matter has changed, generally speaking, the composition of the substance itself has not changed. For example, changes in position, volume, shape, temperature, pressure, and conversion between gaseous, liquid, and solid states.

There are also the interaction between matter and electromagnetic fields, the interaction between light and matter, and the interaction and transformation between microscopic particles (electrons, atomic nuclei, elementary particles, etc.), all of which are physical changes.

When liquid water reaches below 0 degrees Celsius, it condenses into solid ice.

In the case of absorbing heat, the ice will melt into water, and in the case of exothermy, the water will condense into ice, and in the state of the ice-water mixture, the temperature will be kept at 0 degrees Celsius, and the temperature will change when all of it becomes water or all of it becomes ice. Hope it helps.

Water is in liquid form, ice is solid water, and water vapor is water in gaseous form.

In general, there are three states of matter, such as the three states of water are ice, water, and water vapor, which are solid, liquid, and gas, respectively. Of course, there are two other forms of matter that exist called plasma states and super-solids. Substances in the plasma state are called plasmas, and substances in super-solid states are called supersolids.

The radiation state of matter does not include the radiation of matter particles, which in this case refers to electromagnetic radiation. It takes electromagnetic energy as its basic manifestation, and its main characteristics are the propagation of energy and the interaction of participating in matter. One is to change the state of motion of matter, that is, to change the kinetic energy of matter, such as the thermal motion of molecules.

The second is to change the energy state of matter, such as the energy of atoms. In the interaction between electromagnetic energy and matter, we can also find that electromagnetic energy can be absorbed by matter, and it can also be refracted and reflected. In addition to the above properties, high-energy electromagnetic energy can also be decomposed into positive and antimatter pairs, and the positive and antimatter encounters can also be annihilated at the same time and converted into electromagnetic energy.

Liquefaction refers to the process of changing a substance from a gaseous state to a liquid state, which will release heat to the outside world. There are two ways to achieve liquefaction, one is to reduce the temperature, and the other is to compress the volume. The critical temperature is the maximum temperature at which a gas can liquefy.

Since the volume of the gas usually becomes one thousandth of the original after liquefaction, it is convenient for storage and transportation.

Ice is water in a solid state and water vapor is water in a gaseous state.

There are three forms of water: solid, liquid, and gaseous.

Solid: The form of water that can maintain a certain volume and shape, such as ice, snow, frost, hail.

Liquid: A form of matter that can flow, deform, and be micro-compressed, such as clouds, rain, fog, and dew.

Gaseous state: Gaseous states are fluids like liquid states, they can flow and can be deformed, but unlike liquid states, gaseous substances can be compressed, like water vapor.

At normal pressure, the water we usually see is liquid, when the temperature drops below zero, it is solid and ice, and when the temperature is higher than 100 degrees, it is gaseous, which is water vapor. That is, water has three states: solid, liquid, and gaseous.

Ice is solid water that has a certain shape and volume. Ice is colorless, has a certain volume, has a low temperature, and has a hard surface; It has a certain shape, occupies a certain space, and will float on the water. Ice is the solid form of water in nature, and when the temperature is above zero degrees Celsius at atmospheric pressure, the ice will begin to melt and become liquid water.

Water above 4 degrees is in line with thermal expansion and cold contraction. When the water is lower than 4 degrees, it shrinks and expands, resulting in a decrease in density, and when it is greater than 4 degrees, it resumes thermal expansion and cold contraction. This is one of the most important and valuable properties of water.

Difference Between Ice and Water.

First, the similarities.

Both ice and water are colorless and transparent substances.

Second, the differences.

1. Status. Ice: Ice is solid.

Water: Water is in a liquid state.

2. Temperature. Ice: The temperature of the ice is below 0 degrees.

Water: The temperature of the water is above 0 degrees.

Of course, in the north, dozens of degrees below zero, the washed clothes are dried out, and the drying is a disturbance realized by the direct transformation of solid ice into gaseous water vapor. Many objects can be directly converted from solid to gaseous states.

The process of phase transition of matter from a solid state directly to a gaseous state is called "sublimation" in physics

The process of phase transition of matter directly from a gaseous state to a solid state is called "condensation" in physics

Sublimation and condensation require certain conditions to be realized.

a. Sublimation. For example: 1. The process of turning solid iodine into iodine vapor directly when heated is sublimation.

2. Mothballs gradually become smaller is sublimation.

3. Ice is sublimated when heated and directly turned into water vapor.

4. Dry ice is sublimated when heated into gaseous carbon dioxide.

b. Condensation For example: 1. On winter nights, indoor water vapor often condenses into ice crystals on the window pane.

2. The shape of "frost" in nature is slowly trapped.

c. Solid-state --- gaseous inter-conversion

For example: 1. The bulb will turn black after a long time, because the solid filament (tungsten) is heated into gaseous tungsten --- sublimation, the gas touches the glass, and the condensation becomes solid tungsten attached to the bulb glass.

2. Put a small amount of solid iodine in the flask, and heat the flask slightly, the solid iodine does not melt into liquid iodine, but directly becomes iodine vapor. When the heating is stopped, the iodine vapor does not liquefy, but adheres directly to the flask to form a solid iodine. The former is the phenomenon of sublimation, and the latter is the phenomenon of condensation.

The difference between the two is that water vapor is gaseous, colorless, odorless, invisible and untouchable with the naked eye, relatively light in weight, and can be compressed, without a fixed volume; Whereas, water mist is liquid, which is composed of countless small droplets, which can be observed and touched with the naked eye, weighs more than water vapor, and cannot be compressed, and has a fixed volume.

The similarity between water and water vapor is that they are both made up of water molecules, and both are colorless, odorless, transparent, flowing substances, both occupy space, and have a certain weight.

2. The difference between ice, water, and water vapor.

1. Different forms

Ice: Ice is solid.

Water: Water is in a liquid state.

Water vapor: Water vapor is in a gaseous state.

2. The density is different

Ice: The density of ice is 900kgm.

Water: The density of water is 10 kg m.

Water Vapor: The density of water vapor is.

3. The application is different

Ice: Ice should be used in the fields of domestic and industrial cooling.

Water: Water is mainly used in solvents, life support, electronics industry and other fields.

Water vapor: Water vapor is used in life, petrochemical industry, fire fighting and other fields.

Water is a substance necessary for the normal metabolism of the human body, and water has many important functions in the body

1. Water is an important component of cell protoplasm.

2. Water acts as a solvent in the body to dissolve a variety of electrolytes.

3. Water plays a role in transporting nutrients, metabolic wastes and endocrine substances (such as hormones) in the body.

4. Water has high thermal conductivity and specific heat, which can be used as a "heat carrier" to transfer heat between the body and the surface, which helps the human body to regulate body temperature.

The transformation of liquid water into solid ice is determined by a combination of two factors: temperature and pressure.

When the temperature is below the freezing point of water (0 degrees Celsius) and the pressure is appropriate, the molecules of water condense together to form a regularly arranged crystal structure, which is transformed into solid ice.

Yes, the details are as follows:

Curing: snowflakes, ice, frost, frozen lakes.

Liquefaction: rain, snow, flooding.

Gasification: The water vapor of boiling water (evaporation phenomenon).

Water is one of the most common substances on Earth. 71% of the Earth's surface is covered by water. It is an important resource for the survival of all life, including inorganic chemistry and human beings, and it is also the most important component of living organisms.

Water is a colorless, tasteless, and odorless liquid at room temperature.

The density of water is the highest (1000 kg m is often taken in approximate calculations). The density of solid water (ice) is smaller than that of liquid water, so ice can float on the water. When the water freezes, the volume increases slightly.

South-to-North Water Diversion

China's water shortage mainly refers to the north. In particular, in the past 20 years, due to natural changes and the impact of human activities, the trend of more freshwater resources in the south and less in the north has become more serious. The distribution of freshwater resources formed by natural, geographical, meteorological and other factors is difficult to solve by soft science alone.

It has to be done in a hard way. The ongoing South-to-North Water Diversion Project is one of the hard ways.

The solid state of water is ice, and the gaseous state is water vapor. Select A.

Ice is a crystallization formed by the orderly arrangement of water molecules, which are linked together by hydrogen bonds to form a very "loose" (low-density) rigid structure. The spacing between the O—O nuclei closest to the water molecule is that the O—O—O bond angle is about 109 degrees, which is very close to the bond angle of an ideal tetrahedron of 109 degrees 28 minutes. However, the O-o spacing of each water molecule that is only adjacent and not directly bound is much larger, and the farthest one is reached.

Each water molecule can associate with another 4 water molecules to form a tetrahedral structure, so the coordination number of the water molecule is 4.

Water vapor, is the gaseous form of water (H2O). When water reaches its boiling point, it turns into water vapor. At one standard atmosphere at sea level, the boiling point of water is or 212°F.

Water can also slowly evaporate into water vapor when it is below the boiling point. In a very low pressure environment (less than atmospheric pressure), ice will directly sublimate into water vapor. Water vapor may contribute to the greenhouse effect and is a type of greenhouse gas.
