These detectors, used primarily by large commercial or industrial firms, sound only when the temperature rises to a certain level They are not nearly as safe as the ionization and photoelectric types in that the fire must be more intense before the thermal unit will sound
Thermal clothes are specially designed to keep you warm in cold weather. My feet were like blocks of ice despite the thermal socks Thermals are thermal clothes. Have you got your thermals on?
A thermal is a movement of rising warm air. Birds use thermals to lift them through the air. thermal junction thermal spring thermal conduction thermal energy thermal expansion thermal radiation
rising current of warm air caused by or designed to retain heat; "a thermal burn"; "thermal underwear" of or relating to hot a hot spring; "thermal water" relating to or associated with heat; "thermal movements of molecules"; "thermal capacity"; "thermic energy"; "the caloric effect of sunlight
1) Refers to heating and cooling characteristics of building structures 2) Refers to a type of electric generating station or power plant, such as coal and nuclear plants, in which the source of energy for the prime mover is heat
A mass of rising air That's where we go to fuel and gain altitude The best place is to be right in the center Pilots obey rules of the road when flying in a thermal together
Rising bubble of warm air the top of which is usually depicted by a fair weather cumulus cloud Manna to soaring pilots Often found over ROUND-OUT CAFE or if you can stand the bouquet, the pig farm!
