Agas has v= 4.0l, t =27 degree c and p=2.0 atm. what is the v if t=327 degree c and p=8.0 atm?
a 1.0 l
b 4.0 l
c 3.0 l
d 2.0 l
e 5.0 l

As I am reading the problem,i can tell the question gives you two temperatures, two pressures, one volume and asking for the other. this should be an indication that you need to use the following gas formula

P1V1/T1= P2V2/T2

P1= 2.0 atm
V2= 4.0 L
T1= 27= 300 K
P2= 8.0 atm
V2= ?
T2= 327= 600 k

let's plug in the values into the formula

(2.0 x 4.0)/ 300= (8.0 x V2)/ 600 K

V2= 2.0 Liters

answer is D

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.
