Guys for the last page 4 precautions i wrote:
1)the test tube wasn't vertical so some air escaped.
2)finger was alsi immersed so the volume will not be accurate.

1)air bubbles in the test tube.
2)measuring cylinder might not be dry.
wbu?

I put the same for the first three and then I dont remember my last one....

i am definitely positive decreasing since i accurately remember the wording of the question and it said that he fist used 100 and then bla bla decreasing posittiiiiivvve !!!

exactly
you move far away from lamp the temperature will decrease
d was distance between lamp and thermometer
so 10 to 100 accordingly

i wrote both of these answers ( that its hard to take readings from rule as to avoid parallax you have to look from the top of the ruler which is not easy ,,and the mass keeps on falling )

I wrote hard to take readigs from rule...wat u thk?

I wrote measure the diameter of the cylinder, divide by two to find radius 'r' then place the cylinder such that the opposite edges are on 90+r and 90-r respectively.
e.g. if cylinder has diameter 4cm, radius = 2cm and edges are on 92 and 88 so center is on 90

This is like EXACTLY what i wrote ...i also gave all the calculations in variables ..lyk 90+X and 90+X ..etc etc ...and these 2 are where the edges of the cylinder shall be placed ...

Uh
If I remember correctly
The temperatures was INCREASING
It started at 52 and ended around 80-somethign I think.
Therefore should go from 100 to 10 >.>

yeah! That's what ALL the people r saying in different words to confuse other ppl

 

[bluefa1con]

i dont remember exactly but the lowest temp was for 100 and the highest was for 10

Lol

hey guys i got the gradient as 1.647 sumthing ! is it correct

may be couz i got 1.52

 

[areebaization]

may be couz i got 1.52

same here

 

[zaid1q]

i got 1.51....do u think this is acceptable????

 

[areebaization]

i got 1.51....do u think this is acceptable????

yeah It's pretty close! I am pretty sure it will be accepted for the first part

 

[zaid1q]

yeah It's pretty close! I am pretty sure it will be accepted for the first part

what about the second part?

 

[areebaization]

what about the second part?

idk about the second part coz some ppl r saying that u had to write it in 1 significant figure and some say that more than 3 s.f
