when does water after being ecaported turn to water vapor instead of H+ and O ions?

Question

is it becasue of the intermolecular forces

Answer 1

I don't understand your question. Water never H^+ and O6- ions. When liquid water evaporates it becomes water vapor. It still is water and the molecules are intact.

Answer 2

why is it still intact?
is it because of the intermolecular forces

Answer 3

The H to OH bonds don't break that easily. The number of (H^+) and (OH^-) = about 1 x 10^-7 molar which is a VERY small number (1 in 10 million or so) so you can see that most of the water molecules are intact as HOH.
