初中物理中判断冰水混合的最终状态是解这一类题的关键。本文给出简单易于掌握的方法。设水和冰的初温、质量,比热分别为t_1、-t_2 m_1、m_2、C_1、C_2。λ为冰的熔解热。为判断终态,先算出 Judging the final state of ice-water mixing in junior high school physics is the key to solving this type of problem. This article gives a simple and easy to master method. Let the initial temperature, mass, and specific heat of water and ice be t_1, -t_2 m_1, m_2, C_1, and C_2, respectively. λ is the heat of fusion of the ice. To determine the final state, first calculate
