题目:用混合法测定物质比热时,所测得的物质比热一定比真实值偏小.这道题是在初三学习热学知识后,我用来检测学生是否掌握用混合法测定物质比热的实验和原理的.然而,出人意料的是:在我所教的98个学生中,只有27人答对,约占28%.为什么?后经询问学生才知,包括个别答对的学生,他(她)们认为:用混合法测定物质比热 Title: When using the mixed method to determine the specific heat of a substance, the measured specific heat of the material must be smaller than the actual value. This question is used to test whether students master the use of mixed method to determine the substance ratio after learning the knowledge of heat in the third year. Hot experiments and principles. However, surprisingly, of the 98 students I taught, only 27 answered correctly, accounting for about 28%. Why? After being asked by students, including students who answered individually, he ( They believe that the use of mixing method to determine the specific heat of matter
