  2. Temporary work - Wikipedia

    en.wikipedia.org/wiki/Temporary_work

    Temp agencies are a growing part of industrial economies. From 1961 to 1971, the number of employees sent out by temporary staffing agencies increased by 16 percent. Temporary staffing industry payrolls increased by 166 percent from 1971 to 1981, and 206 percent from 1981 to 1991, and 278 percent from 1991 to 1999.

  3. Kelvin - Wikipedia

    en.wikipedia.org/wiki/Kelvin

    The scale was designed on the principle that "a unit of heat descending from a body A at the temperature T ° of this scale, to a body B at the temperature (T − 1)°, would give out the same mechanical effect, whatever be the number T."

  4. Bromine - Wikipedia

    en.wikipedia.org/wiki/Bromine

    At room temperature, bromine trifluoride (BrF 3) is a straw-coloured liquid. It may be formed by directly fluorinating bromine at room temperature and is purified through distillation. It reacts violently with water and explodes on contact with flammable materials, but is a less powerful fluorinating reagent than chlorine trifluoride.

  5. Plasma parameters - Wikipedia

    en.wikipedia.org/wiki/Plasma_parameters

    All quantities are in Gaussian units except energy and temperature which are in electronvolts.For the sake of simplicity, a single ionic species is assumed. The ion mass is expressed in units of the proton mass, = / and the ion charge in units of the elementary charge, = / (in the case of a fully ionized atom, equals to the respective atomic number).

  7. List of temperature sensors - Wikipedia

    en.wikipedia.org/wiki/List_of_temperature_sensors

    The integrated circuit sensor may come in a variety of interfaces — analogue or digital; for digital, these could be Serial Peripheral Interface, SMBus/I 2 C or 1-Wire.. In OpenBSD, many of the I 2 C temperature sensors from the below list have been supported and are accessible through the generalised hardware sensors framework [3] since OpenBSD 3.9 (2006), [4] [5]: §6.1 which has also ...

  8. Speed of sound - Wikipedia

    en.wikipedia.org/wiki/Speed_of_sound

    Mach number, a useful quantity in aerodynamics, is the ratio of air speed to the local speed of sound. At altitude, for reasons explained, Mach number is a function of temperature. Aircraft flight instruments, however, operate using pressure differential to compute Mach number, not temperature. The assumption is that a particular pressure ...

  9. Gas mark - Wikipedia

    en.wikipedia.org/wiki/Gas_mark

    Gas mark 1 is 275 degrees Fahrenheit (135 degrees Celsius).Oven temperatures increase by 25 °F (13.9 °C) each time the gas mark increases by 1. Below Gas Mark 1 the scale markings halve at each step, each representing a decrease of 25 °F.
