Initial volume of the tank of nitrogen (V₁): 14.0 L
Initial pressure of nitrogen (P₁): 1 atm
Final volume of the tank of nitrogen (V₂): ?
Final pressure of nitrogen (P₂): 0.8 atm
Step 2: Calculate the final volume of the nitrogen
We have a gas that undergoes a change at a constant temperature. If we assume an ideal behavior, we can calculate the final volume of the nitrogen using Boyle's law.
