    The container will have a pressure of 8 atm when the temperature is 50 degrees Celsius

    Explanation:

    To calculate this temperature, we need a gas law that relates temperature and pressure.

    This is the Gay Lussac's law and we know from it that temperature and pressure are directly related

    Thus;

    P1/T1 = P2/T2

    From the question;

    P1 = 4 atm

    T1 = 25 degrees celsius

    P2 = 8 atm

    T2 = ?

    Substituting these values, we have;

    4/25 = 8/T2

    4T2 = 8 * 25

    4T2 = 200

    T2 = 200/4

    T2 = 50 degrees Celsius
