Answer

greater than $932^oF$

Work Step by Step

Using $F=\dfrac{9}{5}C+32$ or the Fahrenheit conversion of Celsius, then $500^oC$ is equivalent to \begin{array}{l}\require{cancel} F=\dfrac{9}{5}(500)+32 \\\\ F=900+32 \\\\ F=932 .\end{array} Hence, at $\text{ greater than $932^oF,$ }$ glass is liquid.
