I think , entropy is a measure of the number of specific ways in which a system(keep in mind that the system is thermodynamic) may be arranged. – Parth Lohomi · 2 years, 3 months ago

\[\triangle S=\displaystyle\int \dfrac{dQ_{rev}} {T} \]

\(\triangle S\) is change in entropy...

\(T\) is absolute temperature – Parth Lohomi · 2 years, 3 months ago

LOL why are u following me again? xD -_-Log in to reply

Not understanding Entropy is okay. It is the hardest concept in information theory and thermodynamics.

Entropy is the amount of information in a system.

Can it be equated to randomness? Yes! Because, to store more random arrangements, you need more bits. However, the more the order, the less the entropy. Why? Because to store the arrangement, you just need to know the order.

Which of the following string has more entropy? a) aaaaaaaaaaa b) xyzhwkofgbf c) aaaabbbbccc – Agnishom Chattopadhyay · 2 years, 3 months ago

I guess, The 2nd one. (b)Log in to reply

Nope, Not ever xD xD I wanted to Learn the basics On Entropy. Like, The definition and all. Once I have the Base Strong, I shall move to the Advanced study on this topic. ThanksLog in to reply
