Question 36

A student heats three different substances in an oven set to $∘C100\ ^\circ\text{C}$ and records their states of matter at three stages of the experiment.

Table 1: States of substances during heating

Substance	Before heating	At $∘C100\ ^\circ\text{C}$	After cooling to room temperature
Glass rod	Solid	Solid	Solid
Beeswax	Solid	Liquid	Solid
Pancake batter	Liquid	Solid	Solid

Give a reason why the glass rod did not change state during this experiment.
