2、 Yuanyuan 阅读水的形态变化短文，完成判断、问答任务。
Everything in our world is a solid, a liquid or a gas. Ice and metal are solids. Water and milk are liquids. Air and steam are gases. But things can change.
Ice is a solid. When we take it out of the freezer, the sun heats it. Now it is melting. It is changing into a liquid. Water is a liquid. When we put it in the freezer, the cold air freezes it. Now it is changing into a solid. Water is a liquid. When we heat water, it boils. Now it is changing into a gas. We call this gas steam. Steam goes up into the air.
