小方在化学课上看着酒精灯上跳动的火苗,不禁心存疑问:“每次老师都用酒精灯加热物质,那么酒精灯外焰的温度到底能达到多少呢?(见图1)”下课铃才响,小方立刻和同桌开始讨论课上自己关于酒精灯的疑问。小丽说:“一定高于100℃,因为它能把水烧开。”周边的同学都表示赞许。小方说:那我们上网查查酒精灯加热后能熔化的物质的熔点,就能估计外焰能达到的温度了。同学们
The small party in the chemistry class looked at the flames of light on the alcohol lamp, can not help but wonder: “Each time the teacher are using alcohol lamp heating material, then the temperature of alcohol flame can reach the end of the flame?” (See Figure 1) “The bell was ringing, the small square immediately and at the same table began to discuss their own questions about alcohol lamp. Mary said: ”must be higher than 100 ℃, because it can boil the water.“ ”The surrounding students have praised. Small party said: Then we check the Internet to check the melting point of the substance can be melted after heating the alcohol lamp, we can estimate the temperature outside the flame can reach. classmates
