When the temperature rises, it changes into a liquid state.

当温度升高，它就变了液态。

Earth therefore needed a greenhouse effect to keep its surface warm enough and its water in a liquid state.

因此，地球需要温室效应来使表面保持足够的温暖，并使水保持液态。

This heat then allowed the robots to change between solid and liquid states as well as to move around.

热让机器人得以固态和液态之间转换，还可以四处移动。

" To melt" is to go from a solid state to a liquid state.

“融化”就是从固态变液态。

For using a fuel-cell engine, hydrogen must first be obtained in a pure liquid state.

要使用燃料电池发动机， 必须首先获得纯液态的氢气。

Under the frozen layer, the water remains in its liquid state and oxygen is trapped below the ice.

层下，水保持液态，氧气被困下。

The verb " to melt" (melt) means for something to go from a solid state to a liquid state.

” 动词“融化” （熔化）表示某物从固态变为液态。

The reason is that the hydrogen used in the engine must be obtained in a pure liquid state, which is very difficult to produce and store.

原因是发动机使用的氢气必须以纯液态获得，这种状态的生产和储存非常困难。

Lotty, with Teutonic phlegm, was calmly eating bread and currant wine, for the jelly was still in a hopelessly liquid state, while Mrs. Brooke, with her apron over her head, sat sobbing dismally.

The scale is based on the temperatures which control the physical state of water, with zero degrees Celsius being the temperature that ice melts. In other words, when water changes from a solid to a liquid state.

这个刻度是根据控制水的物理状态的温度来计算的，零摄氏度是融化的温度。换句话说，就是当水从固态变液态时的温度。
