I wrote that the reaction has just started, and the increase in temperature was rapid, so it was hard to determine one certain value at 3 min.
And to why he took from 0-2 min, to measure the initial temperature and ensure a constant temperature.
Wbu?

the same value..dnt rem wht it was
cux the angle was just dependent on conc of sucrose

wbu..
I doubled it, it was 5.05... I made it as 10.1
Thats because the depth decreases, and the saturation of particles increases therefore it doubles

This part was messed up, some made it constant, others doubled it!
But my teacher says it should have been doubled... so idk whats right!
