下列有关对物质的性质的描述与化学性质有关的是（ ）
A．铜具有良好的导电性
B．铁在潮湿的空气里易生锈
C．浓盐酸具有挥发性
D．金刚石是天然最硬的物质
A、导电性不需通过化学变化才能表现出来，属于物理性质，所以错误．
B、铁在潮湿的空气里易生锈，是铁与空气中的氧气、水反应的结果，在这一化学变化中表现出来的性质是化学性质，所以正确．
C、挥发性不需通过化学变化才能表现出来，属于物理性质，所以错误．
D、硬度不需通过化学变化才能表现出来，属于物理性质，所以错误．
故选B．
Girl; Do you want to go to a movie, Edward? Boy;小题1: Girl; What kind of movies do you like? Boy: Well, I like comedies because they're funny. And I think thrillers are great. Girl; 小题2: Boy; No, documentaries are boring.小题3: Girl; I don't like documentaries, either. And I don't like thrillers—they're scary. Boy：小题4: Girl; Well, I like action movies.
