I thought at first that the baloons were in the same room, in which case George was right. But then I re-read the question and with the same amount ie mass of gas in them, the smaller volume must have a higher internal, and thus external, pressure.

I realized I made two wrong choices right after I made my decision, but still I got 84%

We must be a bunch of dummies. I posted this on BXClub and guess what, one guy gets 100% and another 96% but knew the right answers really, just clicked the wrong box because he was too fast.

I'm still confused. Atmospheric pressure on the surface of things is equal to 1 bar, isn't it, no matter what's the internal pressure of the thing?? Or was this not the question being asked?

Hi George
The question went something like, 'all the balloons contain the same amount of gas, which one is in the highest atmospheric pressure' and it would be the smallest balloon because the higher the pressure is that surrounds the balloon, the lower the volume of the balloon will be because the gas inside will be compressed equal to the surrounding pressure. If the gas was in a sealed solid container (such as a gas bottle) it would not change volume when atmospheric pressure changes because the solid container cannot contract and therefore will not squeeze its contents. I havent explained this very well, i think i have now confused myself Dean -------------------- 92 xm 20i prestige auto (modified)R.P 5678

I got 84%. I got some pulley questions wrong and I was caught out by the question about fuel mixture into the cylinder one.

Hi all,
I got 94% the first time too. Some poorly worded and ambiguous questions from our US cousins. What have electrical circuits got to do with a Mechanical aptitude test? List of correct answers attached. Cheers noz  -------------------- '10 '59' C5 2.0 HDi Exclusive Tourer Metallic Grey

Only 88%, but maybe this explains somthing about Fords?
