将质量为m_1、温度为t_1的水,与质量为m_2、温度为t_2的冰,一同放入绝热容器内,如果容器的热容量不计,那水和冰热平衡时的温度是多少? 求解这类冰、水混合最终状态的问题很容易出错,如果直接设共同温度为t,通过热平衡方程式求解,往往会得出荒谬的结果,冰、水混合最终状态的确定对学生并非易事。下面介绍这类问题的一种解答方法。设冰的熔解热为λ,水的比热为c_1,质量为m_1的水
Water with mass m_1 and temperature t_1 is placed in adiabatic container together with ice with mass m 2 and temperature t 2 . If the heat capacity of the container is not counted, what is the temperature of water and ice heat balance? Solve this type of ice The problem of the final state of water and water mixing is very easy to make mistakes. If we directly set the common temperature to t, solving through the heat balance equation will often lead to ridiculous results. The determination of the final state of ice and water mixing is not easy for students. Here’s how to solve this kind of problem. Let the heat of fusion of ice be λ, the specific heat of water be c_1, and the mass m_1 of water
