## rvgupta Group Title explain what is entropy. does it have to do anything with time one year ago one year ago

1. UnkleRhaukus Group Title

entropy is a property of the state of the arrangement

2. sami-21 Group Title

its the measure of disorder of energy of a system .. it always increases for irreversible system, remains constant for reversible system but never decreases ..with the passage of time its increasing ..

3. henpen Group Title

See http://www.physicsforums.com/showthread.php?t=492228 With constant pressure etc. $Entropy=\int\limits \frac{C}{T}dT$

Just from the novice perspective; I would argue that time is a measurement of change; and in order for any system to undergo change, it has to be comparable in time.

5. Fellowroot Group Title

Its an index of how a system becomes disorganized. S=(k)Ln(W), k is the Boltzmann's constant, W is the disorder parameter.

Yes, it has to do with time. Typically as time increases entropy increases.
