    Answer: 0.023 liters

    Explanation:

    Given that,

    Original volume of gas (V1) = 25mL

    [convert 25mL to liters

    If 1000ml = 1L

    25ml = 25/1000 = 0.025L]

    Original temperature of gas (T1) = 22°C

    [Convert 22°C to Kelvin by adding 273

    22°C + 273 = 295K]

    New volume of gas (V2) = ?

    New temperature of gas (T2) = 0°C

    [Convert 0°C to Kelvin by adding 273

    0°C + 273 = 273K]

    Since volume and temperature are given while pressure is held constant, apply the formula for Charle's law

    V1/T1 = V2/T2

    0.025L/295K = V2/273K

    To get the value of V2, cross multiply

    0.025L x 273K = 295K x V2

    6.825L•K = 295K•V2

    Divide both sides by 295K

    6.825L•K/295K = 295K•V2/295K

    0.023 L = V2

    Thus, the new volume of the gas will be 0.023 litres
