English: returned compre paper, got 33/50 (foreva this kind of mark), some ppl get >40, so high lor...chemistry period was goped by lokelf, so she managed to finish going thru the whole compre paper.

Physics: din really pay attention coz i am bz studying bio and revising the facts, i noe she is talking about some magnetic field, about a force that causes the wire to flung out or something, whateva lah, mi reading textbook to get better idea (if i got time)

Maths: continued our integration topic, i think finished everything liao :D

Bio: Biology test on drugs + microorganisms + biotechnology. The essay qn was sort of a surprise to me, but luckily i din have a mental block when answering that qn...wah, heng the whole test i din slack around or do slowly, coz if i did that confirm no time to finish, coz i finished the paper just on time when yipcw was collecting the papers.

Some chemistry knowledge:

Sulphur is a pale yellow, odourless, brittle solid, which is insoluble in water but soluble in carbon disulphide. Sulphur is essential to life. It is a minor constituent of fats, body fluids, and skeletal minerals.

Phosphorus is an essential component of living systems and is found in nervous tissue, bones and cell protoplasm. Phosphorus exists in several allotropic forms including white (or yellow), red, and black (or violet). White phosphorus has two modifications. Ordinary phosphorus is a waxy white solid. When pure, it is colourless and transparent. It is insoluble in water, but soluble in carbon disulphide. It catches fire spontaneously in air, burning to phosphorus (V) oxide. When exposed to sunlight, or when heated in its own vapour to 250°C, it is converted to the red variety. This form does not ignite spontaneously and it is a little less dangerous than white phosphorus. The red modification is fairly stable and sublimes with a vapour pressure of 1 atmosphere at 417°C.
