but the answer given is volume increase , density decrease .. from the times physic
i know why d , when ice > water , temperature increase ... charles law= volume increase , volume is inversely proportional to density This post has been edited by customer2: Nov 20 2010, 01:05 AM |

QUOTE(zeeyang @ Nov 20 2010, 10:26 AM) Wrong concept. First, Charles's Law does NOT apply here. When Ice turns into liquid there's a decrease in volume. my question is when ice melt into liquid , not water turn into ice 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. 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 the answer gaven is when ice melt into liquid , volume increase , density decrease |

QUOTE(Playboy21 @ Nov 24 2010, 07:44 PM) Yeahh.. They woke me up as I was sleeping after my English paper 2 if didnt write orang asli wrong?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.. |
