Question

What is entropy? Explain with examples.

Answer 1

hey !!

Entropy is a measure of uncertainty or randomness.

For example :- Campfire.

Answer 2

Answer:

It is a measure of disorder of molecules (or) randomness of a system.

• It is a state function and extensive property.

• It is denoted by S.
• Change in entropy ΔS= q(rev)/T
• For any isolated system,  ΔS(total) = ΔS(system) + ΔS(surrounding)
• For any spontaneous reaction, ΔS = '+' ve (but not necessary)

           ∴ ΔS(total) = ΔS(system) + ΔS(surrounding)

Ex: Camphor

Hope the answer is helpful :-)
