“萘的熔解与凝固”是初中物理课本中的一项重要分组实验,所需时间长,误差大。其原因主要是由于萘的导热性能差,比热又小的缘故。为了解决上述问题,我认为首先应从改 The “melting and solidification of naphthalene” is an important grouping experiment in junior high school physics textbooks. It takes a long time and the error is large. The reason is mainly due to the poor thermal conductivity of naphthalene and the small specific heat. In order to solve the above problems, I think that we should change from the first
