Question

thermal A special weave called thermal weave traps insulating air in little pockets to increase the warmth of long underwear and blankets. ˈθərməl

Accepted Answer

(1) Of, relating to, or caused by heat. (2) Designed to insulate in order to retain body heat. In days gone by, much of the male population of the northern states in the cold months would wear a garment of thermal underwear covering the entire body, called a union suit. Union suits kept sodbusters, cowboys, and townsfolk alike not only warm but also itchy and a little on the smelly side (back when bathing once a week was considered the height of cleanliness). Thermal imaging is photography that captures “heat pictures”—rather than ordinary light pictures—of objects. And thermal pollution occurs when industrial water use ends up warming a river in a damaging way. Small-plane pilots use thermal as a noun for a warm updraft, often over a plowed field or desert, that lifts their wings, just as it enables hawks to soar upward without moving their wings
