量度固體同埋液體密度步驟！！

Firstly it is important to note that

density = mass / volume

assumed that your solid is insoluble in water (if yes, that use oil instead in the procedure.)

material:
sand (or any solid used)
water (or oil if it is soluble)
beaker


procedure:
1.100 ml of water is placed into the beaker.
2.The sand is weighted and placed in the beaker, the new volume is recorded.

noted that there are sand left out in the transfromation, it may affect the accuracy instead.


For liquid:

procedure:
1. The measuring cylinder is weighted.
2. liquid is placed in the measuring cylinder and the Volume is measured.
3. The measuring cylinder and the liquid is weighted

using the information you can calculate the desity of the liquid and solid.

Note that you have to write the procedure in passive voice.

好呀無問題，希望趕得切啦。首先要知道　密度＝質量／體積如果用的物質能溶於水的話，那麼在測量體質的時候請用油來代替。material（中文唔知係乜…儀器…用既野果ｄ啦。）沙水量筒程序：1. 100ml的水被放進量筒內2. 沙的質量已記錄，再被放進量筒內，新的體積已記錄。新的體積減去100ml的水得知沙的體積, 以質量除體質得出密度。

同樣方法for liquid1. 量筒的重量已記錄2. 液體被放進量筒內，新的體積已記錄。3. 液體和量筒的總重已記錄。再以同樣方法,以總質量減去量筒質量,除以該液體的體積就得出密度啦^^（我的中文不知道有沒有錯…畢竟是功課請努力^^）
