thermal in a sentence

carbon, phosphorus, sulphur - exists in allotropic forms, the particular variety employed should always be stated, as the conversion of one modification into another is frequently attended by a considerable thermal effect. There Can Be No Doubt That The Range To° To 20° Is Too Low For The Accurate Thermal Regulation Of The Conditions Of The Experiment. (2) If the Peltier effect was proportional to the thermoelectric power and changed sign with it, as all experiments appeared to indicate, there would A B be no absorption of heat C in the circuit due to the Peltier effect, and therefore no thermal source to account for the energy of the current, in the case in which the hot junction was at or above the neutral temperature. Wilson, Elements of Thermal Chemistry (London, 1885); P. Duhem, Traite de Mecanique Chimique (Paris, 18 97-99); J. THERMOCHEMISTRY, a branch of Energetics, treating of the thermal phenomena which are associated with chemical change. The reason a thermal imaging instrument helps when hunting ghosts is because it can "see" more than the naked eye. These thermal waters dissolving limestone well had extended the narrow fissures into cave passages through thousands of years. A fourth class of electric wave detector comprises the thermal detectors which operate in virtue of the fact that electric oscillations create heat in a fine wire through which they pass. It's lined with 2mm neoprene, which is considered the highest standard in thermal insulation for aquatic activities. Runners were given thermal blankets to prevent heat loss at the end of the race. Thermal efficiency Overall thermal efficiency is around 30 %. 2. The measurement of thermal diffusivity by laser flash is an alternative way of determining the thermal conductivity of liquid alloys. thermal overloads in your integrated management logs are not pleasant. Beneath these layers are masses of salter water, through which a thermal wave of small amplitude is slowly propagated to the bottom by conduction. The thermal regulation centers of the brain help to maintain the body's internal temperature. anisotropic thermal conductivity of quartz. Subscribe to America's largest dictionary and get thousands more definitions and advanced search—ad free! high accuracy filter radiometers are used in thermal and optical metrology, for temperature measurements, photometry, and derivation of spectral emission. There are several products that offer thermal night vision, including some night vision goggles that are available today. From printed henley and thermal shirts to boisterous t-shirts and patterned woven shirts, you'll find something even if you prefer to stay on the conservative side of loud. 'All Intensive Purposes' or 'All Intents and Purposes'? Cameron discussed the various project ideas with us such as thermal photovoltaics. The graphical representation of the properties of alloys can be extended so as to record all the changes, thermal and chemical, which the alloy undergoes after, as well as before, solidification, including the formation and breaking up of solid solutions and compounds. Project 26: From convection to chaos The early investigations into chaos are intimately tied into the numerical study of problems in thermal convection. With high-density PCM thermal storage technology, it may be possible for a condensing fireless steam locomotive to be developed for extended operating range. of Miliana, noted from the time of the Romans for its thermal springs, occupies a picturesque position 1800 ft. Its high coefficient of thermal expansion, coupled with its low freezing point, renders it a valuable thermometric fluid, especially when the temperatures to be measured are below - 39° C., for which the mercury thermometer cannot be used. With uniform temperature, taking h constant in the gas-equation, dp / dz= =p / k, p=poet/ k, (9) so that in ascending in the atmosphere of thermal equilibrium the pressure and density diminish at compound discount, and for pressures p 1 and 1, 2 at heights z 1 and z2 (z1-z2)11? There are two bathing establishments, one of which preserves remains of Roman baths, and a large military thermal hospital. When using heat implements like blow dryers, curling irons, and flat irons, spray a thermal protectant such as Aquage Beyond Body Thermal Spray to protect your hair from damage. The following table gives the electric conductivities of a number of metals as determined by Matthiesen, and the relative internal thermal conductivities of (nominally) the same metals as determined by Wiedemann and Franz, with rods about 5 mm. Aluminum is a thermal conductor, so in cold weather heat will drain out through the sash, as moisture will condense on interior surfaces. In the first case the thermal effect of 58.58 calories actually observed must be increased by 2d to allow for the heat absorbed in splitting off two gramme-atoms of carbon; in the second case the thermal effect of 96.96 must be increased by d as above. Perhaps one of the most interesting images of this kind is on the cotton rib thermal called BK Bridge. There is also a thermal fuse on the heating element chamber. At low temperatures, there is not enough thermal energy available to allow torsion angle changes, so the conformation becomes frozen in. Thermal Treatment.-The hardening, tempering and annealing of steel, the chilling and annealing of cast iron, and the annealing of malleable cast iron are explained readily by the facts just set forth. Therefore warm, waterproof clothing is absolutely essential, plus, I had forgotten to bring my wetsuit, but fortunately was well-equipped in my, The Victorians had a dream that Whitby could match the gilded splendour of Harrogate, and the, The facade of a building represents the architect's signature, but it is also a source of light and a, We have a major research program to investigate the, And when was the last time you opened up a machine and reseated all the boards to eliminate a. Microjets can be powered by compressed air, Conversion of the photoproduct could be achieved by, For a quarter of an hour they wheeled and circled, rose and sank and effortlessly rose again as the. Thermal Pollution: An often-overlooked type of water pollution is thermal pollution. It has some importance as a thermal station, and the springs were used by the Romans. Copyright © 2020 LoveToKnow. thermal equilibrium, the small deviations from which produce the weather. These variations in the properties of iron are brought about in part by corresponding variations in mechanical and thermal treatment, by which it is influenced profoundly, and in part by variations in the proportions of certain foreign elements which it contains; for, unlike most of the other metals, it is never used in the pure state.
