    Answer: 600°C

    Explanation:

    This reaction is explained by Charles' law as the pressure is constant.

    From the question, we obtained:

    V1 = 67mL

    T1 = 18°C = 18 + 273 = 291K

    V2 = 3V1 (Vol is tripled) = 3x67 = 201mL

    T2 = ?

    Applying the Charles' law,

    V1 / T1 = V2 / T2

    67/291 = 201 / T2

    Cross multiply to express in linear form.

    67xT2 = 291x201

    Divide both side by 67, we have:

    T2 = (291x201) / 67

    T2 = 873K

    Converting to Celsius temperature, we have

    T°C = K - 273

    T°C = 873 - 273 = 600°C
