A gas is at 3 atm, what will be the pressure of the gas if it expands three times?
Correct answer: A. 1 atm
- A. 1 atm
- B. 3 atm
- C. 6 atm
- D. 9 atm
Explanation
Since the pressure of a gas is inversely proportional to volume based on "Boyle's Law", therefore if volume increases by a factor of three, pressure will decrease by a factor of 3, hence 3 atm will become 1 atm.

About Boyle's Law
Boyle's law states that the pressure of a fixed mass of gas varies inversely with its volume when temperature remains constant. Problems use the relationship P₁V₁ = P₂V₂, pressure-volume graphs and volume changes, with constant temperature distinguishing it from Charles's law.
