Second Law of Thermodynamics

A video attempting to explain the second law of thermodynamics in simple non-mathematical terms.

Background: I made this video after hearing from creationists for the umpteenth time that evolution defies the second law of thermodynamics. This is complete and utter nonsense, evolution does not defy the second law of thermodynamics.

The second law of thermodynamics is concerned with the relationship between heat and work; this video explains this and the important points that are made by the second law, namely:
Heat always flows from a hotter body to a colder one.
Perpetual motion in a closed system is impossible.

The song is "The Scientist" by Coldplay.

Coldplay and the Second Law go quite badly together, sorry.

Kirkwhisper you are wrong. The increase in entropy applies over the entire universe. Therefore a slight decrease of entropy here on earth (evolution if you like, or a tree growing) means on overall increase somewhere else (the sun for example)

@jdw3150 You dont know, you believe in something that created us, or you believe you know that something created us.

@jdw3150 however is its very possible to disprove certain definitions of god scientificaly.

Anyone else think its better without the music......not that its bad music.....its good music.....really......

just sort of a distraction....

Don't really get it....Sorry not very smart (me).....

noooobody said it was easssy...=)

@jdw3150

you've just proven your lack of skills to properly argue on a Philosophical debate, but yet toooooo far from proving God. The Khalam argument is falacious. If an uncaused being must exists to prove the existence of a finite being, then why can't the finite being known as Universe be uncaused itself. Your premise is bogus then your whole argument falls as a superfluous construct thats -at best- uneeded on your own terms.

Its funny to see creationist try to use this law to debunk evolution, LOL:

I can't hear myself think or learn!!! STFU Chris Martin!!!!!!

Nice, thanks!

I'm scanning through all of the comments as Coldplay captivates the soundtrack to the argumentative vibe.

@ally0138 "When this energy supply [of the Sun] runs out the entropy of the Earth will increase as it cools to the same temperature as the surrounding space"

Actually, the Earth system's entropy will *decrease* as it is cooled:

Delta S(earth) = -Q(from earth) / T(earth)

Turn off the Sun, heat flows from earth to universe, entropy of earth goes down.

If you have one take away from the second law, may it be the knowledge that entropy and temperature are related.
