when a substance cools, its molecules vibrate at a slower speed and when a substance is heated its molecules vibrate quicker, right?. Is the increase in the molecules vibration a result of the heat energy being applied to it, or is it the increase in the vibrational energy of the molecule what...

but isn't it the hydrogen bonding that keeps the molecules close together in the first place? I mean, water in its liquid and solid states has hydrogen bonding but not in the gaseous state, so i thought that is why there is so much more energy needed to get it from liquid to gas, to break those...

Hi, i am writing a assignment about thermal expansion and contraction and i would like to know if anyone could explain to me why the heat of vaporisation is nearly seven times that of the heat of fusion for water. I thought it might be hydrogen bonding but this is present in both the liquid and...

wow, that's fascinating, so basically all the photons coming from the sun are still exert only 1/15th the power of its gravity upon the earth. So would different wavelengths therefore produce different radiation pressures? Like, if i fired gamma rays or radio waves at my "infinitely sensitive"...

haha, my bad, no paranormal activity going on here :D

If you had an extremely sensitive scale (use your imagination) and shone a beam of light upon it, could you measure the force that the photons were exerting on the scale? would there even be a force?

Hi, first post! OK my question is regarding the synthesis of metal halides, specifically those of Chlorine. If i pass a dry stream of HCl(g) over a bed of heated Al foil will this be an acceptable route to the anhydrous salt? I am thinking of generating the hydrogen chloride from conc H2SO4...
