Question

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?

Answer 1

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
