Why can you smell gasoline a block away from a gas station?
cindy:
1. Why can you smell gasoline a block away from a gas station?
2. Why will a pop can explode if heated?
3. Would a column of mercury be longer or shorter at the top of a mountain? (I don't know what a "column" of mercury is) and why?
4. What will happen to the size of a balloon containing helium when it rises to the atmosphere? why?
thanks to anyone who can help me out on any of these questions! :D Chem's just now what i do best :-[
Mitch:
2.) PV = nRT and when you raise the Tmeperature you also raise the pressure. Once the pressure is high enough, it will explode out of the can.
What science class are you doing this HW for?
cindy:
thanks! this is all for chemistry.. the questions seem kinda weird to me though.. How am i supposed to know why you can smell gas a block away? COME ON NOW! lol
Mitch:
1.) Well the answer is actually somewhat sophisticated dealing with vapor pressures. But, since this is high school, the answer should just be diffusion.
What chapter are you in, in Chemistry?
cindy:
wow, you guys are so amazing :D
ps. the unit is called "the behaviour of gases"
