Interpretation:
The new volume of the balloon as it transitions from an initial volume of 0.75 L and pressure of 1.0 atm to a final pressure of 0.50 atm needs to be calculated.
Concept introduction:
The relation between volume (V) and pressure (P) of a gas under temperature is represented through Boyles Law.
As per Boyles law, pressure is inversely related to volume:

Answer to Problem 12STP
(D) 1.5 L
Explanation of Solution
Given Information:
Initial volume of balloon, V1 = 0.75 L
Initial pressure, P1 = 1 atm
Final pressure, P2 = 0.5 atm
Calculation:
Let V2 represent the final volume of the balloon
Based on equation (1):
The volume of balloon at a final pressureof 0.5 atm is 1.5 L.
