  • scales
  • These measuring devices are gauged in several different ways, with scales based on the freezing and boiling points of water - as well as, in the case of the absolute temperature scale, the point at which all molecular motion virtually ceases. (encyclopedia.com)
  • Empirical temperature scales are historically older, while theoretically based scales arose in the middle of the nineteenth century. (wikipedia.org)
  • Such scales are valid only within convenient ranges of temperature. (wikipedia.org)
  • The term degree is used in several scales of temperature. (wikipedia.org)
  • thermometers
  • Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. (wikipedia.org)
  • Thermometers measure temperature by a number of means, including the expansion that takes place in a medium such as mercury or alcohol. (encyclopedia.com)
  • The temperature of the air near the surface of the Earth is measured at meteorological observatories and weather stations, usually using thermometers placed in a Stevenson screen, a standardized well-ventilated white-painted instrument shelter. (wikipedia.org)
  • relatively
  • Bringing a metal to its forging temperature allows the metal's shape to be changed by applying a relatively small force, without creating cracks. (wikipedia.org)
  • Materials which have useful engineering applications usually show a relatively rapid increase with temperature, i.e. a higher coefficient. (wikipedia.org)
  • characteristic
  • Color temperature is a characteristic of visible light that has important applications in lighting , photography , videography , publishing , manufacturing , astrophysics , horticulture , and other fields. (wikipedia.org)
  • Junction temperature may be measured indirectly using the device's inherent voltage/temperature dependency characteristic. (wikipedia.org)
  • kelvins
  • The color temperature of the electromagnetic radiation emitted from an ideal black body is defined as its surface temperature in kelvins , or alternatively in mireds (micro-reciprocal kelvins). (wikipedia.org)
  • coldest
  • The coldest year so far was 1879, with a mean temperature of 5.9ºC, while the hottest recorded year was 2014, with 10.0ºC. (dmi.dk)
  • Its zero point, 0K, is defined to coincide with the coldest physically-possible temperature (called absolute zero). (wikipedia.org)
  • average temperature
  • The effect of latitude is evident in the large north-south gradients in average temperature that occur at middle and high latitudes in each winter hemisphere. (britannica.com)
  • For most latitudes, however, continentality explains much of the variation in average temperature at a fixed latitude as well as variations in the difference between January and July temperatures. (britannica.com)
  • approximation
  • Because such an approximation is not required for incandescent light, the CCT for an incandescent light is simply its unadjusted temperature, derived from comparison to a black-body radiator. (wikipedia.org)
  • The temperature dependence of conductors is to a great degree linear and can be described by the approximation below. (wikipedia.org)
  • different
  • Heat and temperature , although different, are intimately related. (wiktionary.org)
  • Other places, such as under the arm or in the ear, produce different typical temperatures. (wikipedia.org)
  • The seasonal variation of temperature and the magnitudes of the differences between the same month in different years and different epochs generally increase toward high latitudes and with distance from the ocean. (britannica.com)
  • Extreme temperatures observed in different parts of the world are listed in the table. (britannica.com)
  • The premise is that every system in a datacentre can be equipped with a shared water infrastructure which is divided into multiple stages with different temperatures. (wikipedia.org)
  • The different temperatures are achieved by setting up different liquid cooling technologies with different temperature tolerances in a serial cooling setup as opposed to a single parallel circuit. (wikipedia.org)
  • heat
  • In such a case the measured temperature will vary not only with the temperature of the system, but also with the heat transfer properties of the system. (wikipedia.org)
  • "Warm" in this context is an analogy to radiated heat flux of traditional incandescent lighting rather than temperature. (wikipedia.org)
  • If both have the same temperature, there is no heat, only two objects with high levels of internal energy. (encyclopedia.com)
  • Note that a vacuum was specified: assuming there was air around them, and that the air was of a lower temperature, both objects would then be transferring heat to the air. (encyclopedia.com)
  • The greatest temperature changes occur for dry, sandy soils, because they are poor conductors with very small effective heat capacities and contain no moisture for evaporation. (britannica.com)
  • F. Mean rate of increase of temperature with depth, and mean upward flow of heat. (scientificamerican.com)
  • Somewhat confusing terminology may be encountered in relation to boilers and heat exchangers, where the same term is used to refer to the limit (hot) temperature of a fluid in contact with a hot surface. (wikipedia.org)
  • Incropera & DeWitt Fundamentals of Heat and Mass Transfer, 4th Ed Film Temperature Archived 2009-02-22 at the Wayback Machine. (wikipedia.org)
  • It is proportional to the potential enthalpy and is recommended as a replacement for potential temperature as it more accurately represents the heat content. (wikipedia.org)
  • atoms
  • Because it avoids the abrupt jump from +∞ to −∞, β is considered more natural than T. In many familiar physical systems, temperature is associated to the kinetic energy of atoms. (wikipedia.org)
  • Above the Curie temperature the atoms are excited, the spin orientation becomes randomised, but can be realigned in an applied field, i.e. the material becomes paramagnetic. (wikipedia.org)
  • Below the Curie temperature the intrinsic structure has undergone a phase transition, the atoms are ordered and the material is ferromagnetic. (wikipedia.org)
  • commonly
  • The measure is most commonly applied to the perceived outdoor temperature. (wikipedia.org)
  • The measures are most commonly applied to perceived outdoor temperatures, but also apply to indoors, especially to saunas or when homes or workplaces are not sufficiently heated or cooled or insulated to provide comfortable or healthy conditions. (wikipedia.org)
  • increase
  • Temperature increase causes the fluid to expand, so the temperature can be determined by measuring the volume of the fluid. (wikipedia.org)
  • Most materials expand with temperature increase, but some materials, such as water, contract with temperature increase over some specific range, and then they are hardly useful as thermometric materials. (wikipedia.org)
  • Moreover, since Krafft point is related to solid-liquid transition, better-packed polar heads within surfactant crystals increase Krafft temperature. (wikipedia.org)
  • A positive temperature coefficient (PTC) refers to materials that experience an increase in electrical resistance when their temperature is raised. (wikipedia.org)
  • hotter
  • Since 1988, the majority of years has been hotter than average 1981-2010, and the temperature has shown a sharply rising trend from the 1990s. (dmi.dk)
  • Resistance
  • Originally developed and used by the aerospace industry, HTA alloys are made from a high nickel-content metal with extreme temperature and fatigue cracking resistance. (sae.org)
  • Maximum junction temperature (sometimes abbreviated TJMax) is specified in a part's datasheet and is used when calculating the necessary case-to-ambient thermal resistance for a given power dissipation. (wikipedia.org)
  • neutral
  • For instance in 170 AD, physician Claudius Galenus mixed equal portions of ice and boiling water to create a "neutral" temperature standard. (wikipedia.org)
