    Chemistry Entropy
AI Thread Summary
A spontaneous process can occur where the entropy of the surroundings decreases, typically in exothermic reactions where heat is released, causing a decrease in surrounding entropy. An example includes combustion reactions, where the system releases heat to its surroundings. The condition for equilibrium is that the change in entropy of the system (ΔS_sys) must equal zero, not necessarily that the entropy of the surroundings must also equal zero. For equilibrium, it is not required that ΔS_surr equals ΔS_sys; rather, they can be in a state where their changes balance each other. Understanding these concepts is crucial for grasping entropy's role in chemical processes.

I have two questions regaring my homework assignmnet

1) Is there a "spontaneous process" where the "entropy of the surrounding" decreases?
If so, what kind of reactions (or process) falls into this category? I was trying to
think of something but couldn't/

2) and this was is just to make sure I got it right.. Is it right that the system
is always at equilibrium when [delta S sys= delta S surr].. or do they all have
to euqal to zero?

thanks

any help please?
 
1) Entropy is transferred when one object heats another. Can you think of an example when a system is heated by its surroundings?

2) The condition of system equilibrium is dSsys=0.
 

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...
