where? cuz i might lose 4 too

lel u said it was easier than 2017 xD
n 2017 had a gt of 23 i think so this should go up to 25 lol
there goes my A*

hey y dint the graph support reaction completion at 8 minutes?

i dont think it goes to 25 too high.
and no it doesnt support since a it continued to obsoreb light, it never reached zero absorbtion

haithsoul i googled shit xD
n it says that they both shit in pellets

ohhh ok
lol i got this one wrong too xD
so 4 marks for sure lol

i only seen sheep shit, they should have told us at least

what did you write for the purpose for the water in tube? is it to reduce light intensity to a reasonable one?

ikr they should have :/
idk i just all animals shit the same so i wrote it xD

no its to absorb heat
but i dint write that
i wrote something abt refraction and diverging the rays :/

i wrote that high light intensities could damage the suspension, you think that infers heat?

 

[anastasia grey113]

well idk since u wrote that HIGH LIGHT INTESITIES could damage it
if that had to be controlled, y not just put the lamp further away

wouldnt putting the lamp away prevent high temperatures as well then.

 

[anastasia grey113]

well yes
but wut they want is a high light intensity but no heat
putting the lamp away will lower both and they dont want a lower light intensity

how in the world would a lamp produce so much heat to damage the suspension?

 

[Minsa Fatima]

how in the world would a lamp produce so much heat to damage the suspension?

it is to keep the heat from source constant (to standardise this variable)

 

[haithsoul]

it is to keep the heat from source constant (to standardise this variable)

but you would be changing the distance of the tube to alter light intensities, the further you are from the lamp the less heat so it is not standardized

 

[Minsa Fatima]

but you would be changing the distance of the tube to alter light intensities, the further you are from the lamp the less heat so it is not standardized

thats why we use water to absorb high or low heat as the distance is changed and temp is kept constant

 

[haithsoul]

to be clear are you saying the lamp it self is producing the heat or is it due to high light intensities which make it hot?

Hey there! Don't you think it will continue to absorb light since chlorophyll itself is green so solution remains green. Also it doesn't finish at 8 minutes since it becomes a plateau slightly before 8 minutes, right?

yes it does not finish as the absorption goes to plateau above the zero value

well yes thats wut i wrote too
