    The answer to your question is 2 liters

    Explanation:

    Data

    Volume 1 = 1 l Volume 2 = ?

    Temperature 1 = 25°C Temperature 2 = 25°C

    Pressure 1 = 202.6 kPa Pressure 2 = 101.3 kPa

    Process

    As Temperature 1 is equal to temperature 2 we can use Boyle's law to solve this problem.

    Pressure 1 x Volume 1 = Pressure 2 x Volume 2

    -Solve for Volume 2

    Volume 2 = Pressure 1 x Volume 1 / Pressure 2

    -Substitution

    Volume 2 = (202.6 kPa x 1) / 101.3

    -Simplification

    Volume 2 = 202.6 / 101.3

    -Result

    Volume 2 = 2 l
