Question

At 00 C and 5 atm, a given sample of gas occupies 75 L.  The gas is compressed to a final volume of 30 L at 00 C. What is the final pressure?

Answer 1

At 0°C and 5 atm, a given sample of gas occupies 75 L. The gas is compressed to a final volume of 30 L at 0°C.

solution:

initial state: p₁=5 atm, v₁=75L.

final state: v₂=30L.

according to Boyle's law: p₁v₁=p₂v₂.

p2=p₁v₁/v₂=(5*75)/30=12.5 atm.

The final pressure is 12.5 atm.
