  2. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of natural science, including physics, chemistry, Earth science, astronomy, medicine, biology, ecology, material science, metallurgy, mechanical engineering and geography as well as most aspects of daily life.

  3. Meteorology - Wikipedia

    en.wikipedia.org/wiki/Meteorology

    Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather ...

  4. Temperature measurement - Wikipedia

    en.wikipedia.org/wiki/Temperature_measurement

    A medical/clinical thermometer showing the temperature of 38.7 °C (101.7 °F) Temperature measurement (also known as thermometry) describes the process of measuring a current temperature for immediate or later evaluation. Datasets consisting of repeated standardized measurements can be used to assess temperature trends.

  5. Thermodynamics - Wikipedia

    en.wikipedia.org/wiki/Thermodynamics

    Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics, which convey a quantitative description using measurable macroscopic physical quantities ...

  6. Thermodynamic temperature - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_temperature

    A thermodynamic temperature of zero is of particular importance for the third law of thermodynamics. By convention, it is reported on the Kelvin scale of temperature in which the unit of measurement is the kelvin (unit symbol: K). For comparison, a temperature of 295 K corresponds to 21.85 °C and 71.33 °F.

  7. Thermometer - Wikipedia

    en.wikipedia.org/wiki/Thermometer

    A thermometer is a device that measures temperature (the degree of hotness or coldness of an object) or temperature gradient (the rates of change of temperature in space). A thermometer has two important elements: (1) a temperature sensor (e.g. the bulb of a mercury-in-glass thermometer or the pyrometric sensor in an infrared thermometer) in ...

  8. Weather forecasting - Wikipedia

    en.wikipedia.org/wiki/Weather_forecasting

    t. e. Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century.

  9. Homeostasis - Wikipedia

    en.wikipedia.org/wiki/Homeostasis

    Other normal temperature variations include those related to the menstrual cycle. [19] [20] The temperature regulator's set point is reset during infections to produce a fever. [17] [21] [22] Organisms are capable of adjusting somewhat to varied conditions such as temperature changes or oxygen levels at altitude, by a process of acclimatisation.
