The soil freezes many feet deep over immense areas even in southern Siberia.
The shortness of the summer, the deficiency of drainage and the depth to which the soil freezes in winter, are the circumstances which determine the characteristic features of the vegetation of the tundras.
It fuses at 415° C. and under ordinary atmospheric pressure boils at 1040° C. Its vapour density shows that it is monatomic. The molten metal on cooling deposits crystals belonging to the hexagonal system, and freezes into a compact crystalline solid, which may be brittle or ductile according to circumstances.
The Missouri river is often closed by ice, and the Mississippi at St Louis, partly because it is obstructed by bridges, sometimes freezes over so that for weeks together horses and wagons can cross on the ice.
You'll look around when you get a search warrant, or hell freezes over—whichever comes first!
In the Balkash steppes the winter is very cold; the lake freezes every year, and the thermometer falls to 13° F.
The lake freezes usually at the end of December, or in the beginning of January, so solidly that a temporary post-horse station is erected on the ice in the middle of the lake, and it remains frozen till the second half of May.
It freezes more readily and is not affected by the Mediterranean current.
Nearer the coast, where the melting on the surface is more considerable, the wet snow freezes hard during the winter and is more or less transformed into ice, on the surface of which rivers and lakes are formed, the water of which, however, soon finds its way through crevasses and holes in the ice down to its under surface, and reaches the sea as a sub-glacial river.
It freezes at - 15° to a yellowish crystalline mass; on heating it loses chlorine and forms lead dichloride.
The lake never freezes over, and is less obstructed by ice than the other lakes, but the harbours are closed by ice from about the middle of December to the middle of April.
The freezing-point of sea-water is lower as the salinity increases and normal sea-water of 35 per mille salinity freezes at 28.6° F.
It is only the water that freezes; the dissolved salts are excluded in the process in a regular order according to temperature.
It freezes to a colourless crystalline mass, melting at 10 5°.
It is a colourless fuming liquid of specific gravity 2.269 at o°; it freezes at - 33° C., and boils at I13.9°.
M., and has communication with the open sea by a fairway, a mile and a half wide, which never freezes, and with the tide gives access to the largest vessels.
It often freezes in winter.
In one case (represented by the point A in the figure) the solid which freezes out is a conglomerate of crystals of the compound with those of antimony, in the other case C with those of copper.
The solution then freezes, until the heat liberated is enough to raise the tern perature to the point of equilibrium given by the tendency of the solution taken in contact with ice to approach the true freezing point on one side and the temperature of the enclosure on the other.
Eutectic here freezes 7 Austenite+Cementite Pro-eutectoid Cementite forms progressiuely 882930 1200 0 U a 5 6 ?
So much of either metal as is present in excess over the eutectic ratio, freezes out before the eutectic; (2) that though thus constant, its composition is not in simple atomic proportions; (3) that its freezing-point is constant; and (4) that, when first formed, it habitually consists of interstratified plates of the metals which compose it.
At this point selection ceases; the remaining molten metal freezes as a whole, and in freezing splits up into a conglomerate eutectic of (1) austenite of about 2.2% of carbon, and therefore saturated with that element, and (2) cementite; and with this eutectic is mixed the " primary " austenite which froze out as the temperature sank from v to v'.
As we pass to cases with higher and higher carbon-content, the primary austenite which freezes in cooling across region 2 forms a FIG.
Smaller and smaller proportion of the whole, and the austenitecementite eutectic which forms at the eutectic freezing-point, 1130° (aB), increases in amount until, when the carbon-content reaches the eutectic ratio, 4 30%, there is but a single freezing-point, and the whole mass when solid is made up of this eutectic. If there is more than 4-30% of carbon, then in cooling through region 3 the excess of carbon over this ratio freezes out as " primary " cementite.
The former section, which is too shallow to store up any large amount of heat during the summer, freezes for three or four months along the shores, effectually stopping navigation on the lower Volga, but out in the middle ice appears only when driven there by northerly winds.
The salinity of the water is much less than that of the ocean, containing only 1.05% of salt, and the lake freezes every year for a great distance from its shores.
Thallous chloride, T1C1, is readily obtained from the solution of any thallous salt, by the addition of hydrochloric acid, as a white precipitate similar in appearance to silver chloride, like which it turns violet in the light and fuses below redness into a (yellow) liquid which freezes into a horn-like flexible mass.
Sakhalin is separated from the mainland by the narrow and shallow Strait of Tartary or Mamiya Strait, which often freezes in winter in its narrower part, and from Yezo (Japan) by the Strait of La Perouse.
Wide, which freezes nearly every winter.
It freezes generally from November to April.
In width, with shallow waters of inconsiderable salinity (greatest depth, 22 fathoms), freezes to some extent every year.
The water then freezes in virtue of the cold produced by its own evaporation or by the drying of the moistened wrapper.
It seldom freezes for more than one month, and the harbours are rarely ice-bound.
The river is usually closed by ice from November or December to March or April, and at rare intervals it freezes in October.
1910, p. 798) by treating iron from ferrous oxalate with carbon monoxide, and heating at 150°, is a pale yellow liquid which freezes at about - 20°, and boils at 102.5°.
The harbours and exits of the lake freeze over, but the body of the lake never freezes completely.
The lake never freezes over, though the temperature of the water does not, even in summer, rise far above freezing point.
4 By the middle of September snow flurries have announced the imminence of winter, the smaller streams congeal, the earth freezes, the miner perforce abandons his diggings, and navigation ceases even on the Yukon in October.
The port freezes on an average 127 days every year.
When the oxide-free metal is heated gently in dry ammonia it is gradually transformed into a blue liquid, which on cooling freezes into a yellowish-brown or flesh-coloured solid, potassamide, KNH 2.
