i thinki during eating food , we have to do some sort of work(by our hands and also by our digestive system) & enrgy is produced too........so, may be the amount of energy produced is higher then the amount of work done . also, amount of energy produced is definately higher them that work done because if it is less or equal to that energy produced to, there is no need to hv food..(bcz no extra energy is being supplied to our body)

hence , the problem...( not sure of my answer)

i was wondering

see

lunch gives us energy , i.e we take energy inside , so we have del H +ive , and del S is nt so big as comp. to delH , so by relation

del G = delH - TdelS

delG comes out to be +ive

so non spontaneous

so we have to do smthng to eat lunch

wat say???????????

i had a try , m nt sure

I always like to walk in rain as no one can see me crying there :(

it's simple logic............
 in english free lunch means something acquired without effort or payment or obligation.......
relating this wid thermodynamics
it simply deals wid law of conservation of energy that energy can neither be created nor destroyed but can only be transformed from 1 form 2 d other
but for transformation we hav 2 do some work ... it simply can't happen on its own .......so  no free lunch .......but pay for ur lunch
 
pls tell me if i 'm right .........!!!

but i have promises to keep....

i think no has a PERFECT answer to this question......better to leave it here bcoz they arent goin to ask this type questions in future...leave it himanshu its difficult for you to get a perfectly logical and correct answer but i dont think this should be related to thermodynamics it should be all work and energy sort of thing
cheers!

you work hard for a desired result
