Given a gas is at 1 atm and 20 L, what is the volume of the gas when pressure changes to 3 a 6.7 L 7.6 L 3.0 L 21.0 L

To solve this problem, we can use Boyle's Law, which states that the volume of a gas is inversely proportional to the pressure, provided the temperature remains constant. Mathematically, this can be expressed as: Where:- is the initial pressure (1 atm)- is the initial volume (20 L)- is the final pressure (3 atm)- is the final volume (unknown)Rearranging the equation to solve for : Substituting the given values: Therefore, the volume of the gas when the pressure changes to 3 atm is approximately 6.7 L.
