Understanding Entropy: Diffusion, Evaporation, Mixing, Melting, Separation

AI Thread Summary
Entropy generally increases during processes like diffusion, evaporation, mixing, and melting, as these actions lead to greater disorder in a system. The discussion raises a question about separation, which involves taking a mixed substance and creating pure components, potentially indicating a decrease in entropy due to increased order. However, the overall consensus leans towards viewing separation as an increase in entropy since it often requires energy input and can lead to a more complex system. Participants encourage further exploration of these concepts and welcome corrections to their understanding. The conversation highlights the nuanced nature of entropy in various physical processes.

entropy increases? entropy decreases ? no change in entropy?

diffusion, evaporating, mixing, melting, separation

i think

diffusion - increase

evaporation - increase

mixing - increase

melting - increase

but what about separation :S?


and if anyone thinks any others are wrong do tel me :)

Looks good. When you separate something, you are taking something that is mixed and creating two or more pure things. Does this represent an increase or decrease in organization (order)?
 
decrease?
 
thankssssssssssss it worked:DD)DPD:DD:D:D:D:D:D:

Thread 'Confusion regarding a chemical kinetics problem'

TL;DR Summary: cannot find out error in solution proposed. [![question with rate laws][1]][1] Now the rate law for the reaction (i.e reaction rate) can be written as: $$ R= k[N_2O_5] $$ my main question is, WHAT is this reaction equal to? what I mean here is, whether $$k[N_2O_5]= -d[N_2O_5]/dt$$ or is it $$k[N_2O_5]= -1/2 \frac{d}{dt} [N_2O_5] $$ ? The latter seems to be more apt, as the reaction rate must be -1/2 (disappearance rate of N2O5), which adheres to the stoichiometry of the...

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
