Phasmophobia is a paranormal horror game by British indie game studio Kinetic Games. The game became available in early access for Microsoft Windows with virtual reality support in September 2020. In the game, one to four players work to complete a contract where they must identify the type of ghost haunting a designated site, with several ...
The difference of temperatures between the freezing- and boiling-points of water under standard atmospheric pressure shall be called 100 degrees. (The same increment as the Celsius scale) Thomson's best estimates at the time were that the temperature of freezing water was 273.7 K and the temperature of boiling water was 373.7 K. [33]
Therefore, a degree on the Fahrenheit scale was 1 ⁄ 180 of the interval between the freezing point and the boiling point. On the Celsius scale, the freezing and boiling points of water were originally defined to be 100 degrees apart. A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius.
Examples of other defining points are the triple point of hydrogen (−259.3467 °C) and the freezing point of aluminum (660.323 °C). Thermometers calibrated per ITS–90 use complex mathematical formulas to interpolate between its defined points. ITS–90 specifies rigorous control over variables to ensure reproducibility from lab to lab.
A cryometer is a thermometer used to measure very low temperatures of objects. Ethanol-filled thermometers are used in preference to mercury for meteorological measurements and can measure temperatures in the range of −38 to 70 °C (−36 to 158 °F). Their main physical limitation is the freezing and boiling point of the liquid used.
A degree of frost is a non-standard unit of measure for air temperature meaning degrees below melting point (also known as "freezing point") of water (0 degrees Celsius or 32 degrees Fahrenheit). "Degree" in this case can refer to degree Celsius or degree Fahrenheit.
According to ghost hunters, a cold spot is an area of localized coldness or a sudden decrease in ambient temperature. Temperature decreases claimed to be associated with cold spots range from a few degrees Fahrenheit to over 40 degrees. [59] Many ghost hunters use digital thermometers or heat sensing devices to measure such temperature changes.
Joseph-Nicolas Delisle. The Delisle scale is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). [1] The Delisle scale is notable as one of the few temperature scales that are inverted from the amount of thermal energy they measure; unlike most other temperature scales, higher measurements in degrees Delisle are colder, while lower measurements ...
