Question #114958
A balloon is filled with 10 L of air at a pressure of 1400 torr. What is the pressure of the balloon if the volume is
changed to 5 L?
changed to 5 L?
Expert's answer
According to the combined gas law equation:
p1V1 = p2V2
where p1 - initial pressure, V1 - initial volume, p2 - final pressure, V2 - final volume.
From here:
p2 = p1V1 / V2 = 10 L × 1400 torr / 5 L = 2800 torr
Answer: 2800 torr
