物理图像形象、直观,蕴含丰富的信息,它能描述物理过程,揭示物理量之间的内在关联。物质在熔化和凝固过程中温度随时间变化的图像类问题一直是中考命题的热点,以下结合实例和同学们一起分类例析几道题。一、辨别晶体或非晶体“温度随时间变化”的熔化或凝固图像例1(2016淮安市中考题)如下图所示是某种物质发生物态变化过程
Physical image, intuitive, contains a wealth of information, it can describe the physical process, reveals the inherent relationship between physical quantities. Material melting and solidification in the process of temperature changes over time image class has been a hot topic in the test, the following combination of examples and classmates with a few examples of classification. First, the identification of crystalline or non-crystalline “temperature changes over time ” melting or solidification image Example 1 (2016 Huai’an City Entrance Examination) as shown below is a material state change process
