WHY? A doubt from chemistry (simple....bt m nt getting it)

when eggs are boiled......why delta S is positive.....i asked it to many ppl..........hope i'll get a satisfactory answer here.....:) i know the site is meant for phy and math...bt plzzz help.....

plzzz answer i need it urgently...........plzzz thanking in advance....i request

You are forgetting something. The yolk undergoes chemical reactions to reach that solid state, so you have to take into account the entropy change from breaking some bonds and creating some new ones. I don't claim to have the answer, but when it comes down to such complicated systems, it's not all about random motion.

does this degree of randomness depends over state..........????????????? ....plzzz help...

My guess is that, if you assume that the egg is full, and that its shell is unbreakable, use the 1st law of thermodynamics: dU=TdS-PdV, dV=0 so dU=TdS. Intuitively, U increases as temperature increases. So the change in entropy will be also positive.

bt my doubt..is delta S is degree of randomness of a thing......rite......they say..that as temprature increases the randomness increases bt my do ubt..is on heating the egg yolk solidifies how a particle of egg yolk can perform random motion then.....y it can't b -ve...
