Question

What is a non reacting system in thermodynamics meaning?

Answer 1

Answer:

Laws of Thermodynamics

First Law:

There exists a property of the universe, called energy, which cannot change no matter what processes occur in the universe.  In other words, energy can not be created, nor destroyed by any process…it is transformed from one for to another (for example, entropy to enthalpy).

 

Second Law:

There exists a property of the universe, called entropy, which can only change in one direction no matter what processes occur in the universe.  In other words, all process, if allowed to, will tend to a state of randomized disorder. 

 

At this time, it would be good to give an example of how the first and second laws of thermodynamics interact.  Say we take a new deck of playing cards directly out of the box.  The cards are neatly stacked and arranged in the proper direction.  At this “state”, the cards have the lowest entropy (highest order) possible.  Now, the nicely stacked deck of cards are pushed off a table and scatter on the floor…we have a mess of randomized playing cards that are no longer stacked and oriented in the proper direction.  To put the cards back into their original form, we would have to put work into the system to reduce the entropy (increase the order) until the cards are at the state with the lowest entropy (neatly stacked).

 

Zeroth Law (unusual numbering, I know…):

A universal absolute temperature scale exists and has a minimum value, defined to be absolute zero, and the entropy of all substances is the same at that temperature.  Theoretically, zero degrees Kelvin or Rankin is the lowest temperature attainable (which can not be reached in reality).  At this theoretical temperature, all molecular motion has stopped and all molecules have zero entropy.

ok bro this is correct
