咁實在太 "科學" 吧
0 度係溶緊
突然升到 10 度都係溶緊...

我估大家係看空氣的溫度，又唔係堆雪

主要原因係冰熔化的時候會向周圍吸收熔解比潛熱，令周圍的空氣溫度下降得比平時只有對流(定傳導)勁

大和

我記得阿sir講過 0度結冰定熔冰係睇佢係加熱定降溫

Rookierookie , 有冇聽過一個人放進冰塊中會暖過一個人放進熔冰中?

仲有, 你幾時做左「硬件區板主」 ? =.="

我唔否認係同樣係 ~0C 既時候, 融冰周圍會凍過結冰
但係而家佢想玩現實, 就要跟埋其他現實既規距, 突然大幅回暖唔係無可能

硬件區係今日下午五點幾開始管既 bao_42


實際上應該用 "融"

實際上用熔化
我讀中文版物理bao_05

雖然遲左d,不過都加把口.

melting --> endothermic <-- break H bonding
freezing --> exothermoic <-- form H bonding

By conservation of energy,
melting absorb energy(heat)
freezing release energy(heat)
The energy = latent heat.

therefore Ans is A.

theoretical result =/= experimental result.

因為溶雪時d雪要absorb latent heat from the surrounding,所以温度低了

Good~
但你十個有九個用"溶"
我真係很傷心啊

from the surroundings

也有多多的人缺 s
