我们知道物质可以由固态变为液态,再由液态变为气态,那么物质能够直接从固态变为气态吗?让我们一起来做两个实验看一看.1.碘的升华和凝华实验实验器材:碘锤酒精灯实验步骤:(1)观察碘锤中碘的状态和颜色.(2)在下端微微加热碘锤,观察碘的状态和颜色,观察有没有液态的碘出现. We know that matter can change from a solid state to a liquid state, and then from a liquid state to a gaseous state, so that matter can change from a solid state to a gaseous state? Let’s take two experiments together and see .1 The Sublimation and Condensation Experiment of Iodine Equipment: Iodine hammer alcohol lamp Experimental procedure: (1) Observe the state and color of iodine in iodine hammer (2) Warm iodine hammer slightly at the bottom to observe the state and color of iodine and observe whether there is liquid iodine.
