ask yourself why helium ballons float!

Helium = approx 0.1785g/l
Air = approx 1.25g/l

?? I thought it was 11-plus Chemistry




Youff terday :rolleyes:
Only because they are easier than O levels, before they invented the computer and course work.
dont get me started on the O-level/ Gcse debate :p

It is?! Goodness, maybe the dumbing down stories are right after all then... ;)

Have a look at this anyway: Gases - Densities

Oh, and best of luck with the exams! (Now get back to revising, and stop messing round on t'interweb... ;))
