ｏ．．．．．．．ｊｕｓｔ　ｔｈｉｎｋ　１　ｔｈｉｎｇ
think about why ice melts
When ice is melt, "energy around the surrondings is absorbed"
Therefore, ice can melt, otherwise it only in a solid state

When ice is freeze, it just does nothing.........

Therefore 1st statement is really correct

ps: 溶緊同溶左有好大分別
when ice is melting = 溶緊

所以應於0度附近

正解
或用常識:when ice is melting,the temp around is lower than that of ice.

樓上也補充我所說了

常識來說真係Awor@@"
我以前看d十萬個為什麼都係gum
熔雪仲凍

當ice 溶的時候
即是附近空氣溫度比0度為高
當ice freezes 的時候
即是附近空氣溫度比0低
唔係錯咩
但係你地又講得通喎
ps heat is transferred when there is a temperature difference
isn"t it?

Ron

當ice 溶的時候 >>> temperature 0 degree
當ice 溶左 >>>>>> temperature >0 degree

當ice freeze 的時候 >>> temperature 0 degree
當ice freeze左 >>>>>> temperature <0 degree

而佢問的是 "溶的時候"同 " freeze 的時候", =.="

如果包埋freeze左, 你點講都得,
因為freeze左可以係 -273度, melt緊可以係10000000度
base on 呢d野, freeze 緊又凍過melt緊 la~

所以要清楚題目問咩, 而佢問係freeze緊同melt緊的時候

咳~
唔介意我真係想指出

熔解的熔係火字邊

咁實在太 "科學" 吧
0 度係溶緊
突然升到 10 度都係溶緊...

其實你要咁講, 可以算是蛋蛋找骨頭....=.="
