lol def not what you said Oli... I picked that answer as well Phil, but just took it at face value I was wrong :laugh:

Just got 82%
. Glad all that school work has finally been put to good use :p

i couldn't even open the page does that mean i failed ?

Yep :lol:

got 125 and 126 in iq tests last year. was a bit suprized how bad i did in this. but i guess this is for those who have a very mechanical mind. mine is but not as much as it should be.

Done mine again today as i wanted to see if i done better when awake, the result was a little better, but i guess i am still hopeless.
66% On the first go when sleepy and 78% on the second still failed the test though and i work for Ford:biggrin:

Was expecting to crash and burn but it wasn't as technical as I thought - as Toxo said pretty much all based on stuff from school, GCSE Physics in force!
Seeing as I haven't had anything to do with anything like this for almost 10 years I'm quite pleased with the result!

I reckon, it does not matter how great the surface area is because atmospheric pressure will be equal if 1cm2 or 20m2.
Air pressure will not rise due to surface area
Thats what i thought,
Surely atmospheric pressure is always the same lol

Are you guys talking about the question with the 3 balloons of different sizes and asking which has the higher atmospheric pressure outside the balloon?
As far as I'm concerned the answer is right, if you think of the gas inside the balloon is what is creating pressure and pushing outwards expanding the balloon, and atmospheric pressure is pushing the balloon inwards.
If there is the same amount of gas in each balloon, the internal pressure is identical. Therefore the one with the highest atmospheric pressure is the one where the pressure inside the balloon finds it hardest to oppose the pressure outside the balloon - hence the balloon will be the smallest.
Slightly roundabout explanation but hope that helps explain it - it's absolutely nothing to do with surface area, that's completely irrelevant, it's all about the pressure inside and outside the balloon.
