    Answer:

    The difference between ice and steam in Celsius (Centigrade) is 100 deg.

    So the difference between and 4 cm and 24 cm of the thread corresponds to 100 deg C.

    So 8 cm is 4 cm greater than the ice point

    4 cm / 20 cm = 1/5     since the steam point and the ice point are 20 cm apart

    Then 1/5 * 100  deg C = 20 deg C   the requested temperature
