Question

Can you see water molecules? Are water molecules moving?

Answer 1

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?

Explanation:

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...
