Question

Which of these is wrong? It says I've gotten all but one right. Word bank listed below.

Evaporation is simply molecules leaping nto the air from a liquid. Molecules must achieve two things-- lifting their weight, and breaking a interactions with other molecules. In terms of size smaller molecules should evaporate more quickly than bigger ones. With this in mind, ethanol molecules are larger than waters (see webpage above for observable oddities of water). Going on that ALONE, we would predict that of the two, ethanol should evaporate more slowly However, this is not what is observed Ethanol feels cooler a on the skin and evaporates more quickly. We must look elsewhere for another factor! The secret lies in hydrogen interactions Water makes a ton of them; each of its hydrogen makes at least one. This creates a of interactions holding each water molecule to web several others-- and preventing evaporation. This is why water has an abnormally high boiling point for a small molecule. And it's related to the reason that unlike most solids floats on its liquid (water). While we think of Ce water as 'normal", it's actually a pretty outlandish liquid

Answer 1

The oxygen atom as well as two hydrogen atoms in a molecule of water form hydrogen bonds with neighbouring molecules
