Barometer, the height will be the same.. as for the smoke question it's because it's less dense than air.

Thanks....

Mmm, for the smoke question, I don't think its because air is always less dense at high temperatures ....there is nolink b/w temperature and density....

Do you understand why the freezer in a refrigerator is placed at the top?
Because cold particles become more dense than air, thus they move downwards... so that's how it cools the 2nd fridge chamber under it and vice versa.
Bottom line, smoke has higher temperature.... becomes less dense than air.. and moves upward..
Diablo:
And plus!! Even if you don't understand that concept..... the other selections did not make sense at all....
MaNa:
for the power one i wrote 5 sec one cus less time greatest poswer
n the barometer it was B so obvious
n the eco i wrote the walla which was on the right side
cuz it was the shortest distance:)
am i vorrect?
