Chemistry help!! <gas pressure>?

Question

if you take a 1 liter samle of air from Pike's Peak (4270m above sea level) to death valley (85m below sea level) in a flexible container, how would the following change:

A) mass of the air sample?

B) molecules in the air sample?

C)volume of the air sample?

thanks for all your help guys!!

'preciate it muchoss!!

Answer 1

The mass will NOT change if the container is sealed. For the same reason, the number of molecules will not change. What will happend is your flexible container will be slowly crushed, because the air pressure at top of the peak is far less than it is in Death Valley. So the volume of your sample would decrease considerably. , with everything else listed remaining constant.

Answer 2

A) mass of the air sample? Unchanged

B) molecules in the air sample? Unchanged

C)volume of the air sample? smaller due to pressure increase, but possibly the same or larger if the temperature also increases.

Answer 3

Well... it can't be A or B because the same AMOUNT of air is trapped in the container, so it must be C.

Note also that the gas law (PV = nRT) predicts that the Volume will go down as the Pressure goes up (and, of course, the air pressure DOES go up as you drop in altitude) for a constant amount of air at the same temperature, so that will also give you the answer.

Answer 4

A and B) stay the same!

C) volume will decrease
