物理学中的很多观察和实验都涉及对实验数据的收集和分析处理.如在探究甲和乙两种物质熔化规律时,小明记录的实验数据如表1,请根据实验数据总结归纳这两种物质熔化时温度变化的规律.对实验数据进行分析的方法有多种,但利用坐标图象进行分析是所有数据分析中最直观形象,也是最有效的方法.在温度-时间图象上,描出甲、乙两种物质不同 Many observations and experiments in physics involve the collection and analysis of experimental data, such as the experimental data of Xiaoming recorded in the melting rules of A and B, please summarize these two according to the experimental data There are many ways to analyze the experimental data, but using the coordinate image to analyze is the most intuitional image and the most effective method in all the data analysis.On the temperature-time image, A, B two different substances
