原文：At a certain temperature, a solid begins to change into a liquid.
译文：在一定的温度下，固体开始变成液体。
原文：The temperature, which is solid, changes into a liquid, depends on the substance.
译文：从固体到液体的温度取决于物质。
原文：For water, the solid begins to change into a liquid, when its temperature ris to above zero degrees Celsius.
译文：对于水来说，当它的温度上升到0摄氏度以上时，固体就开始变成液
For some substances such as steel, the temperature at which it becomes a liquid is much higher.
译文：对于一些物质，如钢，它变成液体的温度要高得多。
