How polarity makes water...
and different substances that are polar or ionic. Water's ability to stick to itself is called cohesion, while water's ability to stick to other substances is called adhesion. Now, think back to the initial questions. First, why are some insects able to walk on water?

Quote examples
Richard Thaler
American Economist
In some ways, the finding that financial education doesn't provide long-term payoffs is hardly surprising. After all, how much do you remember from your high school chemistry class? Unless you use chemistry at work, you probably don't recall much about ionic bonding.

Quote examples
Lars Onsager
Norwegian Scientist
Estimates of the ionic mobilities vary over a considerable range; but in any event, the positive ionic defect is much more mobile in the solid than in the liquid, and its mobility varies very little with the temperature.

Quote examples
John Eccles
Australian Scientist
Changes in relative ionic concentration across the postsynaptic membrane are readily effected by altering the ionic composition of the external medium.
