Most everyone would consider wax to be a solid at ambient temperature. “Ambient temperature” is something of a nebulous definition, however. Most scientists would say that “ambient” or room temperature are around 20°C (70°F). Ambient temperature in Phoenix, AZ would be higher but we like to temperature control our dwellings at “room temperature”. The other problem is that paraffin wax has a fairly low melting point…37°C (99°F). Any change in form is more likely to be from higher temperature exposure. It’s still a solid, however.
