Hastening to the attic, the temperature of which was easily hotter than the Gold Coast, you proceeded to mask the windows with a fancy wool coverlet, some khaki pants, and the like, and to ransack the innumerable boxes and barrels stored there.

The ratio of the measured antenna temperature change during a drift scan across the moon to the average brightness temperature of the moon over the antenna beam ( assuming that the brightness temperature of the sky is negligible ) was found, by graphical integration of the antenna directivity diagram, to be 0.85.

The half-intensity diameter of the main lobe of the antenna was about 18'.5, and the brightness temperature was reduced by assuming a Gaussian shape for the antenna beam and a uniformly bright disk for the moon.

A shielded thermocouple was used to measure the upstream temperature of the transpiring gas.

The upper limit was determined by the difficulty of measuring the characteristic anode surface temperature ( see below ) since only a small region of the anode was struck by the arc.

To measure the surface temperature of the anode plug, the surface was scanned with a pyrometer.

Its temperature was denoted by Af.

The mean temperature of this region was approximated by the temperature measured halfways between the edge of the hot spot and the rim of the plug.

The mean temperature of the surface was then computed according to the following relation: Af where x is the fraction of the plug area covered by the hot spot.

The upstream gas temperature measured with the thermocouple shown in figure 2 was Af.

Thus, the dotted line shown in figure 4 was taken as typical for the temperature distribution for all blowing rates.

This temperature was taken as environmental temperature to which the anode holder was exposed as far as radiation is concerned.

It was calculated from the temperature gradient Af at Af inch as Af.

The temperature dependent value of **ye was taken from Ref. 7.

A single value of the thermal relaxation time Af at room temperature was measured by the progressive saturation method.

The temperature was maintained to within about Af for the period of time required to make the measurement ( usually about one hour ).

One sample, which had been exposed to the atmosphere after evacuation at 375-degrees-C, showed the presence of adsorbed water ( about 0.3 wt ) ) as evidenced by a weak resonance line which was very narrow at room temperature and which disappeared, due to broadening, at low temperature.

We know now that a 15-degree differential in temperature is the maximum usually desirable, and accurate controls assure the comfort we want.

Take precautions now, to be sure you avoid those unpleasant and costly heat breakdowns when the temperature zooms this summer.

The standard boiling point is now ( as of 1982 ) defined by IUPAC as the temperature at which boiling occurs under a pressure of 1 bar.

However, unless the airflow is adjusted as well, the flame temperature will decrease because an increased amount of gas is now mixed with the same amount of air, starving the flame of oxygen.

Daniel Gabriel Fahrenheit ( 24 May 1686 – 16 September 1736 ) was a Dutch-German-Polish physicist, engineer, and glass blower who is best known for inventing the alcohol thermometer ( 1709 ) and the mercury thermometer ( 1714 ), and for developing a temperature scale now named after him.

Originally, Iceman's own body temperature would lower dramatically when his powers were active, reaching within a few tenths of a second ( now his body usually converts to organic ice ; see below ).

File: Joule James sitting. jpg | James Prescott Joule ( 1818-1889 ): discovered that heat is a form of energy, ideas led to the theory of conservation of energy, worked with Lord Kelvin to develop the absolute scale of temperature, made observations on magnetostriction, found the relationship between current through resistance and the heat dissipated, now called Joule's law.

Finally in 1724 Daniel Gabriel Fahrenheit produced a temperature scale which now ( slightly adjusted ) bears his name.

The standard temperature is now 68 ° F ( 20 ° C ) but 59 ° F ( 15 ° C ) is an older standard.

By Legendre-transforming this expression, he defined the concepts of enthalpy and " free energy " ( now universally known as the " Gibbs free energy "), a thermodynamic potential which is especially useful to chemists since it determines whether a reaction will proceed spontaneously at a fixed temperature and pressure.

Up to now, it has been almost impossible to foresee the temperature distribution along the cable route, so that the maximum applicable current load was usually set as a compromise between understanding of operation conditions and risk minimization.

On July 10, 1913, a record was measured at the Weather Bureau's observation station at Greenland Ranch ( now the site for the Furnace Creek Inn ), the highest temperature ever recorded in the world.

Highly filled polyurethane elastomers, and more recently unfilled polyurethane foams are now used in high temperature oil filter applications.

In the 1920s, it was discovered that the current through an ideal resistor actually has statistical fluctuations, which depend on temperature, even when voltage and resistance are exactly constant ; this fluctuation, now known as Johnson – Nyquist noise, is due to the discrete nature of charge.

Around 8300 BC the temperature rose drastically, now with summer temperatures around 15 degrees, and the landscape changed into dense forests of aspen, birch and pine and the reindeer moved north, while aurochs and elk arrived from the south.

They now have to view it through a glass panel at the entrance passage, and the tomb is sealed in a temperature and humidity controlled environment.

* In cooling mode the cycle is similar, but the outdoor coil is now the condenser and the indoor coil ( which reaches a lower temperature ) is the evaporator.

On the discharge side of the compressor, the now hot and highly pressurized vapor is cooled in a heat exchanger, called a condenser, until it condenses into a high pressure, moderate temperature liquid.

He worked with Lord Kelvin to develop the absolute scale of temperature, made observations on magnetostriction, and found the relationship between the current through resistance and the heat dissipated, now one of the two laws called Joule's law.

Recent research is now suggesting that the use of spray-drying techniques may be an alternative method for crystallization of amorphous powders during the drying process since the temperature effects on the amorphous powders may be significant depending on drying residence times.

Originally defined as " the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice " ( later 4 ° C ), a gram is now defined as one one-thousandth of the SI base unit, the kilogram, or 1 × 10 < sup >− 3 </ sup > kg, which itself is defined as being equal to the mass of a physical prototype preserved by the International Bureau of Weights and Measures.

Desalination stills now control pressure, temperature and brine concentrations to optimize efficiency.

" The latter statement was broadly accurate at the time, but with additional data and correction of errors, all analyses of satellite temperature measurements now show statistically significant warming.

Since the system is now insulated when the magnetic field is switched off, the process is adiabatic, i. e., the system can no longer exchange energy with its surroundings ( the heat sink ), and its temperature decreases below its initial value, that of the heat sink.
