中学物理教材有关物态变化内容中,明确指出液体的沸点随气压的增大而升高,随气压的减少而降低.但晶体熔点是否与气压有关,教材及参考书中都没提到,以致有学生提出这一
In the physics textbooks for middle schools, it is clearly stated that the boiling point of liquids increases with the increase of air pressure and decreases with the decrease of air pressure. However, whether the crystal melting point is related to atmospheric pressure is not mentioned in textbooks and reference books. Some students raised this
