✔ 最佳答案
CWater and ink particles 都moving, 只不過係d water particles move左你睇唔到
不過這好似係physics 問題

Always remember all particles are ! moving !
C
不是物理,
Form 1就教啦!
The particles of water(liquid) is always moving, but slower than gas particles.
Also faster than solid.As you add the ink(liquid) inside, its particles also moving.
So it spreads out.
好似你將盤藍色彈彈波澈在地上, 它們彈來彈去, 同時將紅色的彈彈波澈在地上,
本來彈來彈去的藍波與紅波一起彈, of cause 中間的紅波會幔幔散擴(彈)出去.

C
應該係physics既(不過中五下的都係數chem)
a錯係因為2隻野都要動
b錯同上
d根本唔關事
