Why does ice melt at room temperature and wax does not?

Ice melts at room temperature because its molecular structure is held together by relatively weak hydrogen bonds, which can be easily broken at higher temperatures, allowing the solid to transition to liquid water. In contrast, wax is composed of long hydrocarbon chains that are held together by stronger van der Waals forces, making it more stable at room temperature and preventing it from melting. Therefore, while ice can transition to liquid form at room temperature, wax remains solid due to its stronger intermolecular forces.
