Answer:
101.4pKa
Explanation:
Given parameters:
Initial Volume of helium = 3.20L
Final pressure of helium = 59kPa
Final volume on helium gas = 5.5L
Unknown:
Initial pressure exerted on the balloon = ?
Solution;
To solve this pressure - volume problem, we simply apply the Boyle's law.
It states that "the volume of a fixed mass gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P1 V1 = P2 V2
Now, insert parameters and solve;
P1 x 3.2 = 59 x 5.5
P1 = 101.4pKa
