A student noticed a yellow, solid, substance was formed when mixing two clear liquids during a lab. What term describes this yellow, solid substance?

A very simple assumption for the specific heat of a crystalline solid is that each vibrational mode of the solid acts independently and is fully excited and thus cv=3NAkB=24.9 kJ / (kmol⋅K). This is called the law of Dulong and Petit.
