parakeets4jesus made a good posting about the 2nd Law of Thermal Dynamics.?

Question

As time goes on, without the addition of energy, entropy increases. There were many of you, in a sarcastic way, who wrote there was an outside source for energy, ever hear of the sun? Well let's look at the sun.

The sun will ruin the roof on your house. It will fade the color of your car. If you stay in it, it will burn your skin, and cause cancer. The sun is very distructive and is used by only one thing on Earth, plants.

As far as evolution, there is a process called disasocitaion, in which the sun breaks down water vapor in the atmosphere into hydrogen and oxygen. This is a very effective way of getting free oxygen in the atmosphere, but it is also deadly to newly forming organisms trying to evolve. Any organisms trying to evolve would be oxidized by this oxygen.

Scientists have also found recently that entropy is as effective in an open system as a closed.

Instead of postings to web sites, could I get comments reflecting the thoughts of you who read this?

Answer 1

WOW, great answer. I'm comment. I'm going to use it a school report.

Answer 2

Plants are not the only living things that utilize sunlight. Ultraviolet light is necessary in the synthesis of vitamin D. Blue light is utilized by one particular DNA repair enzyme.

Dissociation (not "disasocitaion") of water vapor occurs in the upper atmosphere away from almost all life. The bulk of the atmospheric oxygen is generated by photosynthesis in plants.

It's not a recent finding that entropy is "as effective" in an open system as a closed system. Chemical reactions (and other processes) show entropic changes as a function of temperature regardless of whether the system is open or closed. With sufficient input of energy, the tendency to disorder (entropy) is overcome.

Answer 3

Time to hit the books again dude! The sun is used by almost everything on earth. Humans actually generate vitamin D when exposed to sunlight. We have evolution going on around us all the time and have had since life began here, the oxygen, I believe, helped this, not hurt it. The word you are looking for with breaking down water into hydrogen and oxygen is not disassociation. That word means to come apart violently, such as an explosion. The word you are looking for is evaporation. And finally, Entropy, identified as the end of something, and does not apply to a system that is naturally self sustaining, such as our planet.

Answer 4

You seem to be implying that organisms couldn't have evolved because they would have been zapped in the atmosphere. Isn't it more likely that organisms first developed on land or in water where there is a much lower level of free radicals and they would have been able to survive.

Plants aren't the only thing that use the sun:
our skin makes vitimin D using sunlight

Answer 6

yet otherwise of pointing out the 2d regulation is: you could create order from disease, in case you pump IN extra capacity. existence and evolution are a perfect celebration of the operation of the 2d regulation.

Answer 7

i'd love to comment but what exactly is it what the good posting ? can you provide a link ? , on what do you want me to reflect ?
what is the point ? .

Answer 8

oh boy you only think your clever but in reality you are not very clever at all! so I am not going to waste my time trying to educate a close minded man!

Answer 9

I agree, she's got a very good point,so do you, not arguing

Answer 10

God did it. He does everything, He is the Alpha and Omega.
