Morphology

ultrahot = hot (transparent) = ultra + hot

This is a straightforward intensification of 'hot' with the prefix 'ultra-'.

Etymology

Ultrahot joins the first part ultra- meaning 'beyond' with hot meaning 'very warm', the same ultra- you see in ultraviolet. So, ultrahot describes temperatures that are far 'beyond' what we call very hot.
