Water can be a liquid, a solid or a gas. When it is a solid, it can be as hard as stone. When it is a liquid, it can run through your fingers. When it is a gas, you may not see or feel it. Water can change from a solid to a liquid or to a gas easily. Thi
"On one hand, we have developed a novel technique with huge potential to study wetting in general and in particular the force of adhesion between a liquid and a solid, and on the other hand we helped bridge two apparently separate areas of physics (surface physics and mechanics)," Escobar ...

小题1:根据第一段When it is a solid, it can be as hard as stone. 描述,结合常识可知当水是固体时,它被叫做冰,故选D,冰。 小题2:根据第一段When it is a gas, you may not see or feel it. 描述,可知选C。 小题3:根据第二段The heat of the sun turns liquid water into gas from the...
For example, if we choose sort of an arbitrary pressure right about here, and keep the pressure constant and increase the temperature, we start as a solid, but as you can see, just follow the line going to the right. As we increase the temperature, the solid changes to a liquid. And...
