    The kinetic energy (KE) of water molecules only depends on temperature disregard that they are in liquid or solid states. Hence, KE of water molecules in liquid water and in ice are the same.

    2. 温度一樣..動能便一樣..對or錯?

    Yes, it is generally true. The KE of molecules is revealed as the degree of hotness or coldness (i.e. the temperature) of a substance.

    動能(KE)只係睇溫度,溫度一樣,動能(KE)一樣
