Question

assume two cans of differently coloured paint at the same temperature can be mixed together adiabatically. Explain wheather or not the entropy of the system increases, decreases, or stay constant, or whether the second law of thermodynamics is simply not relevant to this situation.

Answer 1

Acc to 2^nd law of thermodynamics:

dS=dQ/T

As the procss is adiabatic, dQ=0

Thus, dS=0.

So, the entropy remains constant.

Answer 2

entropy of the system increases................

because entropy is a second name for randomness.... and colors mixed are said to be more random system than individual color tanks...........

and also 2nd law of thermodynamics is not relevant in this case

Answer 3

dS = dQ/T

If it's an adiabatic process than dQ = 0 and so dS = 0, So entropy remains constant.

The second law of thermodynamics defines a new physical quantity, the entropy.

So, it's relavent.
