The rainy season, which commences in October, continues, with little intermission, until April; and though the winters are generally mild, the mercury seldom sinking below the freezing point
, yet the tempests of wind and rain are terrible.
But the cold was too intense to allow us to do so, for I am convinced that at this great altitude the thermometer cannot have marked less than fourteen or fifteen degrees below freezing point
. What such a temperature meant to us, enervated as we were by hardship, want of food, and the great heat of the desert, the reader may imagine better than I can describe.
"That's one hundred and six below freezing point
- too cold for travelling, eh?"
In a like manner, in Siberia, we have woods of birch, fir, aspen, and larch, growing in a latitude  (64 degs.) where the mean temperature of the air falls below the freezing point
, and where the earth is so completely frozen, that the carcass of an animal embedded in it is perfectly preserved.
The livers were then slowly cooled below the freezing point
, to 21 degrees Fahrenheit, without inducing freezing-thereby supercooling the organ for preservation.
On Friday and Saturday the mercury will drop to about twenty degrees below the freezing point
Adding salt to water lowers the freezing point
, thus preventing the formation of ice.
Because salt lowers water's freezing point
, the leftover water can no longer solidify into crystalline structures at the local temperature, and therefore it remains liquid.
Defend: Water has a freezing point
of 0[degrees]C (32[degrees]F).
The second type of chill happens when the temperature at the end of the solidus reaction starts to fall off and the end of freezing point
has not been reached.
The temperature in the hilly region plummeted several degrees below freezing point
Conditions will generally remain cloudy and foggy, but winds and temperatures are predicted to ease, returning to their normal levels with highs hovering about the freezing point
