地理课件:www.1ppt.com/kejian/dili/ 历史课件:www.1ppt.com/kejian/lishi/ 量筒的使用量液体时,量筒必须
平放。
2. 读数时,视线与量筒内
液面的最凹处保持水平。
若仰视或俯视,会造成读
数有偏差。
3. 量筒不能加热,也不能
装热溶液,以免炸裂。各种测量液体体积的工具量杯烧杯烧杯和锥形瓶比较量杯和烧杯的不同读数时视线应该怎样?人每天喝水的量不能少于1500ml。
老师昨天用自己的水杯喝了两杯,这认为够不够?怎样才能知道呢?医生告诉我们:怎样读出所取液体的体积数?7ml49ml33ml60ml科学知识就在我们的身边,请同学们留心观察,一定会有更多的收获!
