友情提示:今天晚上-1°C!把花收进来把钟的小菜苗盖起来!

后院的水龙头不会被冻裂?

村长大佬,零度的气温能冻裂你的水管?

一克水的温度降低一度需要的能量是一卡。而将一克水转变成冰所需的能量是80卡。水管是接到家里的(20C)。在零度条件下,空气传热可能比你的金属管快吗?

理性推导结论:如果水管会冻坏,你的加油站一块钱卖给我。
 
Frost Warning

Widespread frost tonight.

Conditions will be more favourable for frost tonight as skies clear and winds become light in a chilly Arctic air mass. Temperatures will fall to zero so widespread frost is expected overnight and early Tuesday morning. Tender plants should be protected or brought indoors out of the cold this evening if possible.
