$212^{\circ}~F$
$F = \frac{9}{5}C+32$ We can use this formula to convert from Celsius to Fahrenheit. It is given in the question that $C = 100$ since the temperature on the Celsius scale is $100^{\circ}~C$. $F = \frac{9}{5}C+32$ $F = \frac{9}{5}(100)+32$ $F = 180+32$ $F = 212$ The temperature on the Fahrenheit scale is $212^{\circ}~F$
