It occurs as a white to off-white, crystalline solid, poorly soluble in water, dilute acid and most organic solvents.
水现在处于固体形态。
为什么水变冷时成固体？
固体水的摩尔体积，比液体水的摩尔体积大。
Because the molar volume of solid for water is bigger than that for liquid.
现在，考虑固体，如果水是固体，或者说水要结晶，糖就会从水中分离出来。
Now, if I have a solid, if the water is a solid, it's going to crystallize the water, the sugar is going to be separated from the water.
水的三个形态是：固体、液体和气体。
与纸袋相比，生产塑料袋所需的能量和水更少，产生的空气污染和固体垃圾更少。
Compared with paper bags, producing plastic ones USES less energy and water and generates less air pollution and solid waste.
水冻结成为固体时，我们称它为冰。
质子交换膜燃料电池采用固体聚合物膜为电解质，简化了电池的水和电解质管理；

温度降到零度，水就变成了固体。
冰是水的固体状态。
水结冰时便变成固体。
肥料中，有液体的与固体的品种之分，也还有专门用于水养的肥料的区别。
Fertilizer, there are varieties of liquid and solid divided, there is some specific fertilizer for the water to keep the difference.
冰是固体的水，如果你加热一块冰，它会融化并成液体。
Ice is solid water. If you heat a piece of ice, it melts and turns into a liquid.
水是液体，但我们能把它变成固体。我们还能把它变化为气体。
Water is a liquid, but we can change it into a solid. We can change it into a gas, too.
水在多少温度变成固体？
我们都有发现水可能是固体、液体或气体。
As we all have found out water may be a solid or a liquid or a gas.
我们都有发现，水可能是固体、液体或气体。
As we all have found out, water may be a solid, or a liquid or a gas.
如果行星从恒星那里得到过多热量，行星上的任何水都会像蒸汽一样蒸发。如果得到的热量太少，水就会冻成固体。
Too much heat from its star, and any water would boil away as steam. Too little, and the water would freeze solid.
