利用物理图像可以描述物理规律,利用图象解决物理问题能使问题简化明了,具有形象、直观、清晰的特点.近几年的中考用图像解决物理计算题和选择题不断出现.下面就例析五道图像题.例1室内温度为20℃,此时用浸有少量酒精的棉花裹在温度计的玻璃泡上,随着酒精的迅速蒸发,图1中哪幅图正确反映了温度计渎数随时间的
The use of physical images can describe the laws of physics, the use of images to solve physical problems can simplify the problem, with the image, intuitive and clear features. In recent years, senior high school entrance examination images to solve the physical calculation problems and multiple-choice questions continue to appear. Five images.Example 1 indoor temperature is 20 ℃, this time with a small amount of alcohol soaked in cotton wrapped in thermometer glass bubble, with the rapid evaporation of alcohol, which figure in Figure 1 correctly reflect the thermometer with Time
