Explain what entropy is and how the entropy of the universe is always increasing and how it takes energy to decrease the entropy of a system.

Solutions

Expert Solution

Entropy is Second law of Thermodynamics. In the system thermal energy converted in to Mechanical work.

Second law states that any spontaneous process disorders the system.

Entropy is measure of Disorder.

Energy always flows from high to low.

For example Water always flows from high region to low region.

The temparature is also flows form hot to cold.

We can add energy to solid it will becomes liquid.

In a chemical reaction the more no. of gaseous molecules released. It will tends to entropy of the universe increases.

The Entropy of the system never decrease because it is a spontaneous process.

Once it will interacts with other system then only entropy of the universe decreases.

As far as I interpret it, the law of ever increasing entropy states that "a system will always move towards the most disordered state, never in the other direction". Now, I understand why it would be virtually impossible for a system to decrease it's entropy, just as it is virtually impossible for me to solve a Rubik's cube by making random twists. However the (ever so small) probability remains. Why does this law underpin so much of modern physics? Why...

The law of entropy can also be called the law of increasing disorder; but this law seems to contradict the existence of living organisms that are able to organize chemicals into organic molecules. Explain how living things seem to be able to defy the laws of thermodynamics in terms of the universe's entropy due to life processes and the entropy within a living organism.
