Don't make this mistake! When a liquid evaporates or boils to become a gas, the molecules DON'T come apart! This is true whether you're talking about evaporation, boiling, or vaporization.

Nicely explained, wish all of Chem was taught like this. Just one flaw, there was no explanation of vapor pressure formula. :(

would it be correct to say, that the molecules dont split apart, but the heat turns, one drop of water, into a bunch of little ones? which are now able to fly, being so small? what would pressure do in this equation? im always reading about the Dissociation of salt (sodium chloride) in water creating sodium chloride solution. But it doesnt make much sense, because I cant see how it would do that in our body, which is under pressure. Because salt helps our blood retain the water, and we are still able to send eletrical signals from our brain, which runs on about 5 volts? why is pressure never a factor in these rules of chemistry? which i know nothing about, but im just good at recognizing patterns that dont match up. Hope these questions arent too rediculous. Its how I learn.

It would be easier to say that when water (or any other substance) evaporates, it continues to be water, so the molecules of water maintain their identity and they don't break apart. If they did, they wouldn't be water anymore, but oxygen and hydrogen. Similarly, if gasoline molecules were breaking apart during evaporation, they wouldn't be gasoline anymore, but some other simpler substances, such as methane, ethane, carbon dioxide etc. And if they break apart too into single atoms, there would be no gasoline anymore, but gas carbon and gas hydrogen.

But I wonder... how does it apply to ionic compounds?
From what I observed so far, most ionic compounds are solid in room temperature, and they don't melt easily to become liquid, not to mention boiling to evaporate. But I don't know all ionic compounds out there, so perhaps there might be such which are liquid or which can evaporate. So what about them? What happens when they evaporate? Do their atoms (ions) break apart or not?

Moreover, they fly up not only as molecules,but they fly up as small droplets too.

Some compounds do decompose before they hit the boiling point though.

Thank you so much. I was explaining this exact thing to some curious kids but told them the wrong one... now I can go correct my mistakes. But seriously, I've been looking on YouTube for at least an hour and you are the first person that explains this... at least clearly for us not so smart folk.

Yeah its true that liquid gasoline will not change when they bcome gas, but if there are combustion reaction, they will change,
