Wrong concept. First, Charles's Law does NOT apply here. When Ice turns into liquid there's a decrease in volume.

You cannot use charles's law when there involve a change of state in between like liquid > ice.

General Knowledge:
1) When water turn into ice, there's an increase in volume.
2) Hence, a decrease in density. (P.S. refer Bio form4 textbook chapter 4)

Haven't you all done a question about a floating ice cube on water(with part of it above water surface)? when the ice cube melts, water level will still remains the same. This is because liquid have higher density +  lower volume than the same mass of ice.  smile.gif

Refering to the question above, I have no idea why this happens unless youre heating the water well above 0 degree (say like heating it until 80). Then the answer is possible.

Btw, did I ever mentioned? I am a SPM student as well  thumbup.gif

hi need help here
i thought this question answ should be D?
why is it B?

coz water density is more than oil , light travel slower in denser medium , so it bent towards normal

Yeahh.. They woke me up as I was sleeping after my English paper 2 tongue.gif

And for that inhibitants bit, I answered BOTH orang asli, flora and fauna. Haha..

Good luck for sejarah guys. And concentrate on the teori kedatangan Islam bit for your essay. As well as they kesan, and cara penyebaran. Apart from that, just read through the langkah pembentukan Malaysia and about Nabi. That's what my teacher told me to read, but don't rely on it too much. Nanti macam BM pulak..
