Hello, i'm new here, whats the ans to the wet plates then mother tell u to put on rack question?! What r 2 reasons?

Reason 1 : More surface area for evaporation

Reason 2 : Water can drip on to the rack thus there would be less water to evaporate .

Anyone can still remember the gravity question? Whats your answer? :scratchhead:


help pls!!

[ProteX]

Ya. Firstly, there is more water than the air and CO2 is only >1% of the air, so how can water be depleted before CO2.

[Little Brown]

but in transpiration, only a little amount of water is given out. so how can that little amount of water, in gas form, can fill the water (liquid)? can anyone tell me why it is not water if the answer is carbon dioxide though im not so convinced?

Ya, i think you are right. I put water :(. At first, I thought that when plants photosynthesize, they can respire and produce more CO2, so I put water. However, I think CO2 is better... Oh no!!
