A 3.0 L sample of gas at 400 K and 2.0 atm is compressed to 1.0 L at constant temperature. What is the new pressure?
A.6.0 atm
B.1.5 atm
C.3.0 atm
D.2.0 atm
Explanation
Core Concept
Boyle's law: P₁V₁ = P₂V₂, so P₂ = (2.0 atm × 3.0 L) ÷ 1.0 L = 6.0 atm. Shrinking volume to one-third triples the pressure.
Correct Answer
A6.0 atm
