點解兩塊冰用壓力撞埋一齊然後放鬆兩舊冰會痴埋?/

Since increase of pressure will lower the melting point of ice.

When the two ice cubes are pressed together, a layer of water will be formed between them because of the lowering of melting point that makes the ice melts.

When the pressure is released, the layer of water freezes again and the two ice cubes thus fuses together.

好似唔係melting point既問題
可能係我錯
唔係因為water vapour in air between two ice
變左做ice 所以痴埋左
