Question 1149000: when the temperature stays the same, volume of gas is proportional to the pressure of a balloon filled with 350 cubic inches of gas, at pressure 14 pounds per square inch, find the new pressure of gas if the volume is decreased to 70 cubic inches?

You can put this solution on YOUR website! Let the new pressure be x.
According to Boyle's law PV=constant at constant temperature.
PV=P1V1
Plugging in the values we get 350*14=70*x
Solving we get x=70
The new pressure is 70 pounds per square inch.
please notice that the Boyle's law relates to the gas in the closed cavity
(when the mass of the gas is a constant value in the experiment (!) )
and the Boyle's law states that the pressure of the gas in the cavity is INVERSELY proportional
to the gas volume under the given condition.
The posted problem consider varying mass of the gas in the balloon.
So, it is totally different situation from that which is considered in the Boyle's law.
The posted problem is formulated EXTREMELY unprofessionally --- it is why I didn't even try to answer it.
It is out of any known Physics/Chemistry gas laws --- it is simply some formal fictitious Math (NOT PHYSICS (!) ) situation,
and I do not recommend to any of tutors to answer this GIBBERISH --- this quasy-mathematical exercise/fantasy doesn't deserves any attention.
When you hear from somebody "volume of gas is proportional to the pressure",
close your ears and sweep this person away, since he (or she) does understand NOTHING in what he (or she) is saying . . .
