When I turn on the tap and fill a glass, do I not see water molecules? Likewise when I boil the kettle, do we not see water molecules condensing?


Of course we see it in the bulk phase...but the bulk phase certainly consists of water molecules.... As to whether we can visualize individual water molecules the answer is no. A water molecule has an actual size of less that #3xx10^-10*m# along its longest axis, which is well below our ability to resolve...

And water molecules are moving, even in the condensed phases...
