O, oh!
I think my earlier answer is wrong. The towel and newspaper is to be used as filter. The answer may be in this link :anon123:
I want to know ans for qns 34
It's about 'someone' is in a jungle,all the fruits and plants cant be eaten he only have the following items to produce drinkable water:
.Plastic Sheet
.Newspaper
.Towel
.String
What should he do?
Help me with this qns pls..... :idea:

but to filter thru towel means lot of water needs to be collected. say 200 ml atleast. Other wise the towel would soak up most of the water.
newspaper if used as filter may just tear.

TY! Now still have fever but luckily started having it on the last day!
Don't think too much, remember to drink more water and have a good rest.desichan352:
I got fever today....
Temp. -> 38.7 degrees
Haiz..... But of course I still insisted on taking the paper so they put me in a classroom to take all by myself...
Paper was quite ok except for a few questions here and there
But i was very giddy so could not think properly

Nope. So what if matter has mass? Have you come across something that is so not dense that it completely floats above the water? By stating that water occupies space and the water only goes up to l, it means that w/o the bottle, the water will fill up to a certain volume, but after the bottle has been added in , the volume of water + bottle + stuff inside bottle is the same as water bfr, so obviously, water has to be less, thrfr answer = matter occupies space. <-- if you want standard answer
On the other hand, if you mean mass as in volume, you might get partial marks... <-- \"scientific\" answer... -
please… help me find out whats the 30mcq answer pls… i really need it very much… please… i count on u all le

U can't be referring to volume when u use the term mass. It would be evident to the marker ur scientific concepts are distorted (no offence!)Polar bear:

Matter has mass and occupies space. Mass and Volume are two different things.
Solid, liquid and gas have definite mass.
Solid and liquid have definite volume but not gas. -
Mass = how much space a certain object occupies. Isn’t that vol.?

I think I did not do well in my Science examination or perhaps all my examinations. I am feeling very dejected and heartbroken as I do not think I stand a chance in getting to my dream secondary school. I cry secretly to myself at night. I will just hope for the best and wait till the 25th of November with my fingers crossed. Any comforting words to console me? Your words would make me feel much much better. By the way, thank you to the person who help me answer the questions I asked in the previous post. I got some questions wrong. So sad.
The saddened student,
