    Answer:

    469.9K

    Explanation:

    Using Charles’s law equation:

    V1/T1 = V2/T2

    Where;

    V1 = initial volume (ml)

    V2 = final volume (ml)

    T1 = initial temperature (K)

    T2 = final temperature (K)

    Based on the information provided:

    V1 = 280.0ml

    V2 = 440.0 ml

    T1 = 26.0°C = 26 + 273 = 299K

    T2 = ?

    Using V1/T1 = V2/T2

    280/299 = 440/T2

    0.936 = 440/T2

    T2 = 440 ÷ 0.936

    T2 = 469.9K
