Carbohydrate in the form of sugar proves to be an ideal food for yeast, and 70 to 90 degrees Fahrenheit is the temperature at which the most rapid growth occurs. When these conditions exist and a sufficient amount of moisture is provided, yeast grows very rapidly and produces fermentation.
As he said this he looked at the thermometer. The mercury had risen from 65 degrees Fahrenheit, the normal temperature of the interior of the Astronef, to 93 degrees, and during the half-minute that he watched it rose another degree. There was no mistaking such a warning as that. He had brought two little liqueur glasses in his pocket from the saloon.
Oliver Wendell Holmes remarked to the present writer, like the different thermometrical scales; it does not take very long to realise that twenty-five degrees of Réaumur mean as great a heat as ninety degrees of Fahrenheit. Such a city as Boston amply justifies its inclusion in a "Historic Towns" series, along with London and Oxford; and it is by no means a singular instance.
The climate is one of the least changeable in the world; the sea breeze blows day and night, and throughout the year the day temperature does not vary more than five or six degrees, the average being about eighty-three degrees Fahrenheit in the shade. In 1850 the town of Honolulu was little else than a native village of grass and mat huts. Two or three merchants had good houses.
He lighted all the reluctant gas-jets in the vast gilt chandelier, and in less than half an hour the temperature of the place rose to at least sixty-five Fahrenheit, with every promise of going higher. Mrs.
I am not sure but the monotony of being anchored off there in the bay, the monotony of rocks and precipices that goats alone can climb, the monotony of a temperature that scarcely ever, winter and summer, is below 55 or above 75 Fahrenheit indoors, might drive one into lunacy. But I incline to think it is due to the handsome Capri girls.
A. Yes; at the atmospheric pressure, about a cubic inch of water has to be supplied to the boiler for every cubic foot of steam abstracted; at other pressures, the relative bulk of water and steam may be determined as follows: To the temperature of steam in degrees of Fahrenheit, add the constant number 458, multiply the sum by 37.3, and divide the product by the elastic force of the steam in pounds per square inch; the quotient will give the volume required.
At 32 degrees Fahrenheit, and far below that temperature, oxygen and hydrogen are elastic gaseous bodies, whose particles tend to rush away from one another with great force. Water, at the same temperature, is a strong though brittle solid whose particles tend to cohere into definite geometrical shapes, and sometimes build up frosty imitations of the most complex forms of vegetable foliage.
"It is very much," replied Barbicane; "the temperature which was observed in the polar regions, at Melville Island and Fort Reliance, that is 76@ Fahrenheit below zero." "If I mistake not," said Nicholl, "M. Pouillet, another savant, estimates the temperature of space at 250@ Fahrenheit below zero. We shall, however, be able to verify these calculations for ourselves."
Carelessness, or over-anxiety to put him in the water as quickly as possible, has frequently, from his being immersed in the bath when the water was too hot, caused him great pain and suffering. From 96 to 98 degrees of Fahrenheit is the proper temperature of a warm bath.
