【摘要】 火星题材的电影和科学研究中,水一直是一个热度不减的课题。最新Science报道火星南极冰盖下存有液态水,结合物理化学中的相图,三相点和冰点区别,克拉贝龙方程,稀溶液凝固点降低公式等知识点分析,可以更好地理解文献报道的内容,激发学生的兴趣,利用科研热点和知识点结合的模式,从而全面提高学生的综合能力。更多还原

【Abstract】 In the movie and scientific research of Mars, water is a hot research topic. The latest literature in Science reported that liquid water exists beneath the Antarctic ice cap on Mars. Combining the phase diagram of pure water in Physical Chemistry, the difference between water triple-point and freezing point, the Clapeyron equation, freezing-point depression and other knowledge points, we can understand the contents of the research report well. The combination mode of research hotspots and teaching knowledge points is beneficial to cultivate students’ interest and the comprehensive scientific thinking ability of high school students.更多还原
