I couldn't understand how you say methane has more entropy than it's components.
In this formula 2H2+C-->CH4
We have 3 mole of reactions and mole of production. so obviously methane has less entropy than 2 hydrogen molecules and 1 carbon and tends to break it's bond.
If temperature be enough...
According to below site:
http://hyperphysics.phy-astr.gsu.edu/hbase/Therm/entrop.html
Concept of entropy is that nature tends from order to disorder in isolated systems.
Now you said me which one is more disorder?
a) a isolated vacuum room with a methane molecules (this figure)
b) a isolated...
A gas molecule is made of atoms. we have permission for talking about entropy of it's atoms in the room.
Therefore, are you saying we couldn't understand a isolated vacuum room with a methane molecule inside it thermodynamically?
If true, is there any approach in physics for understanding and...
My question is how does it get energy? there is nothing in the room except a methane molecule.
there isn't any photons. there isn't any atoms.there isn't any molecules. room is like a vacuum and room is isolated. room can not exchange any matter and energy.
breaking bond means violate first law.
Hello Pf's members
Suppose we isolated a methane's molecule at a room with 213 kelvin.
According to second law, methane's molecule tends to break it's bond for reaching whole system (methane's molecule and surroundings) to maximum entropy.
On the other hand for breaking these bonds we need...
Hello PF's members
I know a magnetic field doesn't work on charged particles if magnetic field being perpendicular to the velocity of the particles. also i know magnetic field doesn't work if a charged particle enters with right angle into the field.
But suppose that a charged particle like...

I know it, But i said we need a genetic code for making a functional protein.
The probability of generate this code by random mutation is 1 in 1074?
1.All of proteins in organisms that selected by evolution are a functional...
1.Above sentence means in 1074 mutations(Events) just one of them could make a functional protein and that mutation is beneficial?
2.Is above sentence similar to "Hoyle's calculation of the Odds of Life", thus the criticism against Hoyle's idea can apply to above sentence?
Like this:
Temperature of universe at Planck time was 10^32 K.
http://www.uni.edu/morgans/astro/course/Notes/section3/bigbang.html
If mass of universe was more than Planck mass, the temperature of universe couldn't be 10^32 K.
Planck mass times c square gives us Planck energy.
Amount of Planck energy is 1.956 * 10^9 J.
Was this total energy of universe at plank time at big bang cosmology model?
It's clear this amount of energy is not enough for making our solar system, even it's not enough for making mass of me ( 60 kg ).
Should we postulate energy increase in the...
