小明根据生活经验,提出了自己的疑惑:物质的黏性大小与什么因素有关呢?他认为可能与温度高低有关,于是他设计了如图所示的实验方案:将蜂蜜分装在三个小瓶内,一瓶放在冰箱中,一瓶放在室内的桌上,另一瓶放在微波炉内加热一会儿,然后找来三支相同的试管,用三支相同的滴管分别从三个小瓶中各取一滴蜂蜜,分别同时滴到倾斜度相同的三支相同试管口的内壁上,观察比较各滴蜂蜜流到试管底部所需时间长短,并记录实验数据如下表:

蜂蜜处理

则 可 知 (    )

A:蜂蜜黏性随温度升高而增强    

B:蜂蜜黏性随温度升高而减弱       

C:蜂蜜黏性强弱与温度无关              

D:因本实验观察的是时间而不是黏性,不能确定黏性与温度的关系
