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 !!!

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

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 ...:D :D :D

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 >.>
