What is the difference between melting and melting

First, the reference is different.

1. Melting: refers to the process of changing a substance from a crystalline phase to a liquid phase.

2. Melting: The process by which one substance (solute) is uniformly dispersed in another substance (solvent).

3. Melting: refers to the process of solid absorbing heat and turning into liquid.

Second, the source is different.

1. Melting: Wei Wei "Zhuang Xingji: The Flower of Happiness Blooms for the Warriors": "Does he live for the individual and for the few, or does he fuse his individual into the collective, live for the collective, for the majority." ”

2. Melting: Ye Shengtao "Offline: A Youth": "When the ice touches the spring temperature, it melts into ripples. ”

3. Melting: Lao She, "How I Write Erma": I wrote to him, saying that I was melting the literary language into the vernacular, so as to improve the vernacular, and make the vernacular a thing that can be appreciated by both the elegant and the vulgar. ”

Melting: When the temperature rises, the thermal movement energy of the molecule increases, resulting in the destruction of crystallization and the process of changing the substance from the crystalline phase to the liquid phase.

Melting: (ice, snow, etc.) turns into water.

Melting: The process of phase change of matter from solid to liquid state.

Melting generally refers to the conversion of solid water into liquid water, and melting and melting are synonymous.

Addendum: In fact, people now have a misunderstanding that there is no dissolution in the change of the state of matter, and the word dissolution itself is wrong, and the dissolution in people's mouths means melting.

Melting refers to the molecules that make up the substance, so that the anionic bonds connected by the molecules are broken, producing ions that can move freely (so we say that the melt can conduct electricity, for example, potassium nitrate crystals can conduct electricity when heated to a molten state), and melting refers to the increase in the distance between the molecules that make up the substance, and the molecular ion bonds will not break, and melting refers to the solution composed of solutes (such as sodium chloride) and solvents (water) in a strict sense (that is, the process of sodium chloride dissociating chloride ions and sodium ions in water), Let's say that sodium chloride dissolves in water, and all three are physical changes (no new substances are produced).

"Melting" is colloquial (non-standard), and "melting" is the process of changing the state of matter from a solid state to a liquid state, and it is a process of changing the state of matter, which requires heating, so the word fire is used. If the ice is heated to melt into water, the wax is heated to melt.

"Dissolution" refers to the dissolution of solids, the diffusion process of a solid substance dispersed into a single molecule or ion in another liquid substance. This process does not require heating, but there must be liquid, so it is "dissolved" with three points of water.

"Melting" at room temperature is when a solid substance melts after reaching a certain temperature and becomes a liquid state, which is called a molten state. Unstable at room temperature. (chemical terminology).

When a solid is heated to a certain extent and turns into a liquid, it is called melting, also known as melting. Melting is a morphological transformation of crystals in nature, usually referring to the transformation of ice or snow into water, or the dissolution of solids. The conditions are very different.

The meaning of melting: it refers to the process in which the kinetic energy of the thermal motion of the molecule increases when the temperature rises, resulting in the destruction of crystallization and the change of substance from crystalline phase to liquid phase; It is a first-order phase transition with an increase in enthalpy, entropy, and volume.

The temperature at which melting occurs is called the melting point or melting temperature. The melting temperature range of small molecule crystals is very narrow (generally less than 1), while the melting temperature of polymers is often a wide range due to incomplete crystallization (generally 10 20).

Principle:

The ignition point of raw fibers.

Heat of combustion, flame temperature.

and oxygen restriction index, which have a decisive role in the degree of flammability and the spread and expansion of fire. Some fibers are melted by heat while burning, and they are separated from the fire source like candle oil.

It has a relieving effect on combustion, but if the melt comes into contact with **, it will cause serious burns that are difficult to peel.

Synthetic fibers have melting problems, fabrics blended with cellulose fibers.

In the test, it is possible to do not drip molten matter, but the problem of sticking burns** still exists, after flame retardant finishing, or adding flame retardant to the synthetic fiber spinning solution.

It can make the synthetic fiber meet the flame retardant requirements, but the melting point changes little.

The above content refers to Encyclopedia - Melting.

1. Melting refers to the transformation of ice or snow into water due to temperature or sunlight.

1. Turn into liquid.

The ice cream melted in the sun.

2. For example, ice and snow change from frozen to liquid.

Spring is coming, and the ice in the creek is melting.

2. Melting is the process of changing the substance from a solid state to a liquid state, and it is a process of changing the state of matter, which requires heating, so it is "melted" next to "fire". For example, when ice is heated to melt into water, the wax is heated to melt, sometimes called melting.

3. Dissolution refers to the dissolution of solids, which refers to the process of dissolving solids in liquids, and dissolution Specifically, it refers to the diffusion process of a solid substance dispersed into a single molecule or ion in another liquid substance. This process does not require heating, but there must be liquid, so it is "dissolved" with three points of water. For example, sugar is dissolved in water to make sugar water.

Dissolving: A solid is placed in a liquid to dissolve. It also refers to the turning of ice, snow, frost, etc. into water.

Melting: A solid (e.g., iron, wax, etc.) becomes liquid, gelatinous, or powder due to heat.

Melting: Generally refers only to the turning of ice, snow, frost, etc. into water, and is also used as a metaphor.

Dissolve. Zhuyin: róng huà

Explanation:1The solid dissolves when it comes into contact with water.

2.Solids such as snow and ice become liquids.

3.Dissipate; Decompose.

4.It dissolves and disappears.

Dissolve in water or other liquids: Dissolve. Dissolve. Solution. Solvent. Karst cave.

2) Transformation: change in nature or morphology: change. Split apart. Rigidity. Civilize. Melt. Melt.

Melt. Zhuyin: róng huà

Explanation: The phenomenon of a substance changing from a solid state to a liquid state. The crystal is heated under a certain pressure, and when the temperature rises to a certain value (called the melting point), the crystal begins to melt, and during the melting process, although it continues to absorb heat, the temperature remains the same until it is completely melted into a liquid state.

When the amorphous substance is heated, the temperature continues to increase rather than the crystalline gradually softens and finally becomes liquid, so the amorphous substance has no melting point at all.

Both melting and melting refer to the transformation of matter from a solid state to a liquid state, but there is a difference between them.

Melting is when ice or snow turns into water due to temperature or sunlight. Melting refers to the process of heating a substance from a solid state to a liquid state.

That is, in the process of transforming a substance from a solid state to a liquid state, if it is heated, it is "melted". If it is not heated, it is "melting".
