Entropy کا حساب کیسے لگائیں

Entropy کیا ہے؟

Entropy measures disorder or randomness in a system. The second law of thermodynamics states that entropy in an isolated system always increases over time.

اکثر پوچھے جانے والے سوالات

Can entropy decrease?

Not in isolated systems; local entropy can decrease only if overall system entropy increases elsewhere.

Why is entropy related to disorder?

Higher entropy states have more possible molecular arrangements; organized systems have fewer arrangements.
