熔化热

Heat of melting

熔化热

Melting heat, also known as melting heat, is the unit mass of material from solid to liquid, the body absorbs the heat. The temperature at which the object melts is called the melting point. Melting heat is a latent heat, in the process of melting, the material continues to absorb heat and temperature unchanged, it can not be directly detected by the temperature changes in the heat. Each substance has a different heat of fusion. Crystals have a fixed melting point at a certain pressure and also have a fixed heat of fusion; amorphous, such as glass and plastic, do not have a fixed melting point and therefore do not have a fixed heat of fusion. In the same substance, the liquid has a higher internal energy than the solid state, so that during the melting process, the solid matter absorbs heat to convert it into liquid. Likewise, when the material changes from liquid to solid, the same energy is released. Liquid particles in the liquid compared with the solid, received a smaller intermolecular force, and therefore have a higher internal energy. The value of the heat of fusion is, in most cases, greater than zero, indicating that the object absorbs heat upon melting, exotherm in solidification, and helium is the only exception. Helium-3 at a temperature of less than 0.3 Kelvin, the heat of fusion is less than zero. Helium-4 at a temperature of 0. 熔化热,亦称熔解热,是单位质量物质由固态转化为液态时,物体吸收的热量。物体熔化时的温度称为熔点。 熔化热是一种潜热,在熔化的过程中,物质不断吸收热量而温度不变,因此不能通过温度的变化直接探测到这一热量。每种物质具有不同的熔化热。晶体在一定压强下具有固定的熔点,也具有固定的熔化热;非晶体,比如玻璃和塑料,不具有固定的熔点,因而也不具有固定的熔化热。 同一种物质中,液态比固态拥有更高的内能,因此,在熔化的过程中,固态物质要吸收热量来转变为液态。同样,物质由液态转变为固态时,也要释放相同的能量。液体中的物质微粒与固体中的相比,收到更小的分子间作用力,因此拥有更高的内能。 熔化热的数值在大多数情况下是大于0的,表示物体在熔化时吸热,在凝固时放热,而氦是唯一的例外。氦-3在温度为0.3开尔文以下时,熔化热小于0。氦-4在温度为0.

Definition of 熔化热 in the Chinese dictionary

Melting heat mass per unit mass of crystalline material at the melting point becomes the same temperature of the liquid material required to absorb heat. Also equal to the unit mass of the same species, in the same pressure under the melting point from liquid to solid by the release of heat. Common unit of coke / kg. 熔化热 单位质量的晶体物质在熔点时变成同温度的液态物质所需吸收的热量。也等于单位质量的同种物质,在相同压强下的熔点时由液态变成固态所放出的热量。常用单位为焦/千克。
